Deprecate feature flag for Log threshold alert details page (#172554)

Resolves https://github.com/elastic/kibana/issues/172379

- Deprecates following feature flag used for enabling/disabling Log
threshold alert details page:
```
xpack.observability.unsafe.alertDetails.logs.enabled
```
- Removes usage of this flag from code.
- Adding this flag in `kibana.yml` will generate following warning:
```
[WARN ][config.deprecation] You no longer need to configure "xpack.observability.unsafe.alertDetails.logs.enabled".
```
