rvm failing to install gpg keys on m1 machine

[brainbicycle]

Orb version:

2.1.0

What happened:

I updated the machines in our circle ci jobs from macos.x86.medium.gen2 to macos.m1.medium.gen1 and the ruby install started failing with this error:

/bin/bash: line 8: gpg: command not found
Network error: Unable to receive GPG keys. Will attempt again (1/3)
/bin/bash: line 8: gpg: command not found
Network error: Unable to receive GPG keys. Will attempt again (2/3)
/bin/bash: line 8: gpg: command not found
Unable to receive GPG keys, FAILING

Exited with code exit status 1

Expected behavior:

Ruby version should install as before.

Additional Information:

There was a previous issue with some other reports of the issue but it was closed: #39

Can confirm, getting the same error as mentioned above.

Using:

  macos:
    xcode: '15.2.0'
  resource_class: macos.m1.medium.gen1

Bump.

This PR would fix this issue, btw: #139
