docs: fix incorrect URLs for resetCache and OTel guide ()
### Describe Your Changes

This pull request fixes incorrect URLs in two places:

1. In the OTel guide, which has been corrected in
https://github.com/VictoriaMetrics/VictoriaMetrics/pull/6880, but one
incorrect URL is still missing.
2. In the URL example, the cache reset endpoint for vmselect / Cluster
version is `/internal/resetRollupResultCache`, but it is mistakenly
noted as `/select/internal/resetRollupResultCache`, which misguides the
user. (introduced in )

### Checklist

The following checks are **mandatory**:

- [x] My change adheres [VictoriaMetrics contributing
guidelines](https://docs.victoriametrics.com/contributing/).

### /api/v1/admin/tsdb/delete_series
**Deletes time series from VictoriaMetrics**
Note that handler accepts any HTTP method, so sending a `GET` request to `/api/v1/admin/tsdb/delete_series` will result in deletion of time series.
Single-node VictoriaMetrics:
```sh
curl -v http://localhost:8428/api/v1/admin/tsdb/delete_series -d 'match[]=vm_http_request_errors_total'
```
The expected output should return [HTTP Status 204](https://datatracker.ietf.org/doc/html/rfc7231#page-53) and will look like:
```sh
* Trying 127.0.0.1:8428...
* Connected to 127.0.0.1 (127.0.0.1) port 8428 (#0)

Cluster version of VictoriaMetrics:
```sh
curl -v http://<vmselect>:8481/delete/0/prometheus/api/v1/admin/tsdb/delete_series -d 'match[]=vm_http_request_errors_total'

The expected output should return [HTTP Status 204](https://datatracker.ietf.org/doc/html/rfc7231#page-53) and will look like:
```sh

VictoriaMetrics accepts `limit` query arg for `/api/v1/series` handlers for limiting the number of returned entries. For example, the query to `/api/v1/series?limit=5` returns a sample of up to 5 series, while ignoring the rest. If the provided `limit` value exceeds the corresponding `-search.maxSeries` command-line flag values, then limits specified in the command-line flags are used.

### TCP and UDP
#### How to send data from OpenTSDB-compatible agents to VictoriaMetrics
Turned off by default. Enable OpenTSDB receiver in VictoriaMetrics by setting `-opentsdbListenAddr` command-line flag.
*If run from docker, '-opentsdbListenAddr' port should be exposed*
Single-node VictoriaMetrics:
```sh
echo "put foo.bar.baz `date +%s` 123 tag1=value1 tag2=value2" | nc -N localhost 4242
```
Cluster version of VictoriaMetrics:
```sh
echo "put foo.bar.baz `date +%s` 123 tag1=value1 tag2=value2" | nc -N http://<vminsert> 4242
```
Enable HTTP server for OpenTSDB /api/put requests by setting `-opentsdbHTTPListenAddr` command-line flag.
Single-node VictoriaMetrics:
```sh
curl -H 'Content-Type: application/json' -d '[{"metric":"foo","value":45.34},{"metric":"bar","value":43}]' http://localhost:4242/api/put
```
Cluster version of VictoriaMetrics:
