PR Description

Fix link to Flow Mode in docs:

[tpaschalis]

I'm preemptively approving, but leaving it to @clayton-cornell for the final decision.

I'm not sure why the link is not working here; does it have to do with it being inside of the admonition block?

[clayton-cornell]

@d4nyll Thanks for spotting this one. It slipped through on me.

The link is failing to render correctly because it's inside a note block, and the link definition is set in a doc/reference ta the bottom of the topic. We are using the doc/reference link definitions here because we mount the Static topics in the OSS documentation and in the Grafana Cloud documentation... and we need some special handling for linking so everything work in both doc locations.

The simplest fix here is to simply remove the link from the Note. We have this link elsewhere within the same topic so we aren't loosing anything.

Also... we can't update directly within this .md file because this particular _index.md is a generated topic. The change needs to be applied in the parallel template file _index.md.t

So do you want to roll back this change and apply it to the _index.md.t file? Or we can close this PR and open a new PR that just changes the template file.

Hmmm... looking deeper into this one, and it looks like the fix is a bit complicated because it happened right around when we templated this _index.md file. So the mistake exists in _index.md in the v0.37.1 release and then it was carried over in the conversion to the templated file in main (tagged to next). So I'll close this PR and fix it in the template in main and then manually change the original file in v0.37.1 in a second PR.

Closing this PR. Thanks for finding this mistake @d4nyll The fix took a little fiddling and two separate PRs to get it all right. :-)
