Update manual.adoc

decidim seems to work with Ruby 3.0 and later now (didn't succeed to install decidim gem with ruby 2.7.5, I've received the advice to use ruby >= 3.0)

Thank you for your contribution!

We recently already fixed this issue at #9916. Could you see that change and let us know if it solves the problem for you?

We still need to push the latest version of the documentation site live in order for that to appear at docs.decidim.org.

Now its published, I've launched the deploy manually. Check it out @vmingam and let us know if now its working. Thanks for the fix!!

@vmingam, It seems that proposed patch has a conflict. Can you rebase your work with the latest develop?
Also, can you provide some feedback to @andreslucena's question in above comment?

I'm closing this PR as we've been waiting for feedback for a few months and this should be fixed now. Thanks for the suggestion @vmingam!!
