HTML5: Need mapping between released runtime and branch

[caroparo]

I've been experiencing a bug on surface draw_clear_alpha which caused HTML5 to render incorrectly.
With branch master-feb-23 I cannot reproduce it, but I don't know how to find a matching branch to runtime v2023.2.1.90 where I see the issue.

Could you please add some guides to the README file? Thanks!

I'd suggest using proper release tags for clarity.
