[Issue]: Actually explain which versions will be available in ECH

[jakommo]

Type of issue

Missing information

What documentation page is affected

https://www.elastic.co/docs/deploy-manage/deploy/elastic-cloud/available-stack-versions

What happened?

The bookmark and title for What Elastic Stack versions are available suggest to explain which version are available in ECH, but it only explains the version schema.

Action

• Verify the # and qualifications of versions we make available, and then ... ▼
• Update this section of the doc to explain which versions we make available + remove/reduce the major/minor/patch info to critical info.

I.e. I think in the past we used something like: We make the two latest minor versions of the latest major version available for provisioning in the UI. In addition, the latest minor version of the previous major version is also available.

old options we don't want to do

* We should either rename bookmark and title to reflect the actual content.

• Or at least indicate that this is explained in "2 Maintenance" under https://www.elastic.co/support/eol. We basically have this a bit hidden in https://www.elastic.co/docs/deploy-manage/deploy/elastic-cloud/available-stack-versions#ec-version-policy-eol, but it's not obvious to the user why this is split across two different section in the top and bottom of the doc.

I ran into this again today while someone reaching out to me confused about the ECH version policy.
@shainaraskas I see you moved this on the GH board last week. Does that mean someone will look into it soon-ish?

@jakommo I'll bump the priority but it's not on our roadmap in the next couple of sprints

I'm happy to raise a PR with the text from my second bullet, unless you have other plans for that page(?)

@jakommo feel free to open something. thank you 🙏
