* Update for latest Gleam
- Gleam releases now use LLVM triplets for platforms so the download
URLs have been updated accordingly.
- Gleam's rebar3 support has been removed.
This change means that future versions of this action cannot download
older versions of Gleam. I can make it backwards compatible, but I will
need help from someone who can convert the shell script into PowerShell
for Windows.
* Support older Gleam versions
* Remove rebar from Gleam
