Revert "replaced global http refs with relative markdown ones (#6692)"
This reverts commit 537266363a.

Reason for revert: relative links in docs are much harder to maintain in consistent state
comparing to absolute links:

- It is non-trivial to figure out the proper relative link path when creating and editing docs.
- Relative links break after moving the doc files to another paths, and it is non-trivial
  to figure which links are broken after that.
- The updated relative links do not work properly right now in the docs.
  For example, the https://docs.victoriametrics.com/victorialogs/quickstart.md#building-from-source-code
  link at https://docs.victoriametrics.com/victorialogs/changelog/ leads to 404 page.

This is documented at https://docs.victoriametrics.com/#images-in-documentation .

## Install Recommendation
It is recommended running the latest available release of VictoriaMetrics from [this page](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/latest),
since it contains all the bugfixes and enhancements.
There is no need to tune VictoriaMetrics because it uses reasonable defaults for command-line flags. These flags are automatically adjusted for the available CPU and RAM resources. There is no need in Operating System tuning because VictoriaMetrics is optimized for default OS settings. The only option is to increase the limit on the [number of open files in the OS](https://medium.com/@muhammadtriwibowo/set-permanently-ulimit-n-open-files-in-ubuntu-4d61064429a), so VictoriaMetrics could accept more incoming connections and could keep open more data files.
## Filesystem
The recommended filesystem for VictoriaMetrics is [ext4](https://en.wikipedia.org/wiki/Ext4). If you plan to store more than 1TB of data on ext4 partition or plan to extend it to more than 16TB, then the following options are recommended to pass to mkfs.ext4:
```sh
mkfs.ext4 ... -O 64bit,huge_file,extent -T huge
```
VictoriaMetrics should work OK with other filesystems too.
## Operating System
VictoriaMetrics is production-ready for the following operating systems:
* Linux (Alpine, Ubuntu, Debian, RedHat, etc.)
* FreeBSD
* OpenBSD
* Solaris/SmartOS
There is an experimental support of VictoriaMetrics components for Windows.
VictoriaMetrics can run also on MacOS for testing and development purposes.
## Supported Architectures
* **Linux**: i386, amd64, arm, arm64, ppc64le
* **FreeBSD**: i386, amd64, arm
* **OpenBSD**: i386, amd64, arm
* **Solaris/SmartOS**: i386, amd64
* **MacOS**: amd64, arm64 (for testing and development purposes)
* **Windows**: amd64
## Upgrade procedure
It is safe to upgrade VictoriaMetrics to new versions unless the [release notes](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/latest) say otherwise.
It is safe to skip multiple versions during the upgrade unless release notes say otherwise. It is recommended to perform regular upgrades to the latest version,
since it may contain important bug fixes, performance optimizations or new features.
It is also safe to downgrade to the previous version unless release notes say otherwise.
The following steps must be performed during the upgrade / downgrade procedure:
* Send SIGINT signal to VictoriaMetrics process so that it is stopped gracefully.
* Wait until the process stops. This can take a few seconds.
* Start the upgraded VictoriaMetrics.
## Backup Recommendations
VictoriaMetrics supports backups via [vmbackup](https://docs.victoriametrics.com/vmbackup/) and [vmrestore](https://docs.victoriametrics.com/vmrestore/) tools. There is also [vmbackupmanager](https://docs.victoriametrics.com/vmbackupmanager/), which simplifies backup automation.
