Update MAINTENANCE for post-1.0 world

[Lorak-mmk]

After 1.0 many parts of the document became outdated.
This PR updates them, and simplifies some stuff (for example, there is no longer a difference between instructions for minor / major / patch release).

Fixes: #1264

Pre-review checklist

• I have split my patch into logically separate commits.
• All commit messages clearly explain what they change and why.
• I added relevant tests for new features and bug fixes.
• All commits compile, pass static checks and pass test.
• PR description sums up the changes and reasons why they should be introduced.
• I have provided docstrings for the public items that I want to introduce.
• I have adjusted the documentation in ./docs/source/.
• I added appropriate Fixes: annotations to PR description.

Probably the easiest and best way to review is to read the whole new version of the document, instead of looking at the diff @wprzytula @muzarski

Materialized views + tablets combination is not supported in 2025.1 (it is going to be supported in 2025.2). Did you bump scylla version in CI recently?

We just fetch the latest available docker image. I can see there's been an upload 8 hrs ago: 2025.1.0.

I don't get it, was the support dropped? We did not get such an error with 6.2.
