Subject: [PATCH] Fix regex for ERTS_BIN substitution in Elixir

Something must have gone wrong during testing of the ELixir 1.13.2 patch I submitted last week. Apart from #53707, I also found out that the whole substitution regex did not work. This works better - it is still more brittle than I like, but apparently `substitute*`
does not work with fully anchored regexes.
