Subject: [PATCH] .github: Introducing the Infix Release General

Similar to the standard build workflow, with the following exceptions:

 - Sets internal variable 'ver' to ${GITHUB_REF#refs/tags/v}, for filenames
   and directories, ensuring the leading 'v' in the tag is dropped
 - Sets INFIX_RELEASE variable, for post-image.sh, to '$ver' so it creates
   the .img files with the same name as the tarball and directory. (RELEASE
   clashes with OpenSSL's release handling, breaking builds completely.)
 - Sets release directory + tarball to infix-$variant-$ver, where variant
   is one of "classic" or "" (for NETCONF).
 - *Skips the tests*, for now.  We release from main, which should already
   be tested.  Future releases may run a release test suite here
 - Each build step (matrix) uploads its artifacts, when all build steps
   have completed we start the release job (depends on build), which then
   downloads all the various artifacts before creating the GitHub release
 - The release notes are derived from the file ChangeLog.md.  Please note,
   extraction of the first release notes will fail since there is no prior
   release marker in the file
