Adjust regexs for release tool job

[sxa]

          Look at recommendations for expressions for filenames in RELEASING.md vs the examples shown in the job (Particularly in terms of the sources tarball and inclusion of testimage files)

Possibly only have the information in the job parameter description or RELEASING.md ... Could be either in the releasing guide or the job (Perhaps better in the job as you have it on screen when you're running it). Or sort it out properly via a higher level release job that has fewer parameters and is easier to run, encompassing all of the appropriate logic.

As a follow-on to this, could we move the regular expressions into source control and have the user pick platform names rather than attempting to get the regex correct?

regular expressions into source control

That would be part of a separate effort to make this a pipeline job which is already underway by @sophia-guo IIRC

have the user pick platform names rather than attempting to get the regex correct?

Yep that was the goal of this issue.
