Support Semeru distribution

[vlsi]

Description:

Support Semeru (IBM) Java distribution. It would allow testing Java with IBM JIT.
The suggested flow:

a) distribution: 'semeru'
b) or even treat distribution: 'adopt-openj9' as an alias to semeru (and print a warning to encourage users to migrate to semeru)

Justification:

Adopt-OpenJ9 has been deprecated, and Temurin does not ship distributions with OpenJ9 JIT.
The suggestion is to use https://developer.ibm.com/languages/java/semeru-runtimes/ instead of Adopt-OpenJ9

Are you willing to submit a PR?

I might submit a PR, however, I would like to know if such a PR is desirable at all.

Big +1. I think Alex closed his issue too early (#239 (comment)).

Hello @vlsi. Thank you for your report. We have no objections to add this functionality. We'll appreciate if you submit a pull request.

@dmitry-shibanov I'd say you inadvertently removed the adopt-openj9 distribution by not updating its name.
You did the same with the adopt/adopt-hotspot to temurin transition. I do not understand why you would not handle the adopt-openj9 to semeru transition in a similar way and now see this as a feature request. For me this is a BIG regression instead, because out of nowhere my distribution does not get updates anymore, whereas the other distribution DOES get updates ­-- both without any announcements.

Kindly continue support both alike instead of asking for PRs -- that would be much more user-friendly. Thanks :)
