Install Hex and Rebar per OTP release

[wojtekmach]

See hexpm/hex#1069

I've manually executed release scripts from the Hex PR so the following URLs are already working and thus this can be tested locally.

• https://builds.hex.pm/installs/hex.csv
• https://builds.hex.pm/installs/1.17.0/hex-2.2.1-otp-25.ez
• ...
• https://builds.hex.pm/installs/rebar.csv
• https://builds.hex.pm/installs/1.18.3/rebar3-3.22.0-otp-25

this should be no longer necessary once this PR is released, e.g. in next Elixir 1.18.x.

Looks like I am getting those kinds of issues with 1.18.2: #14662

The fix mentioned above has been released in 1.18.4, could you try 1.18.4?

Please note that Elixir 1.18.2 doesn't support OTP28.

Oh, thank you, looks like distributions like MacPorts should not ship elixir 1.18.2 and OTP 28 at the same time.
