Docs-Add ElasticSearch Troubleshooting

Closes #65386

See merge request gitlab-org/gitlab-ce!31343

* Added elasticsearch.md
* Added reference to guide in Troubleshooting section

Instead of highlighting all lines when not all of them are
needed, only highlight specific lines.

The `BlobPresenter#highlight` method has been updated to
support `since` and `to` params. These params will be used to
limit the content to be highlighted.

Modify `Gitlab::Highlight` to support `since` param which will
then be used to determine the starting line number.

Fix Admin area user access level radio button labels

See merge request gitlab-org/gitlab-ce!31154

In the admin user edit form, access level radio button labels didn't have
the correct 'for' value. Clicking on the label did not select the radio
button. This makes usability a bit nicer since the click area is increased
when the label is clickable.

These branches are frequently updated and automatically deployed to real
environments, there's not really a benefit to building review apps for
them that never get used.
