CI: Ruby 2.5 runs on macos-13 (amd64)

[olleolleolle]

Run old Ruby on a version of macOS which is for amd64.

This gets macOS tests for Ruby 2.5 to green. 🟢

Error: CRuby < 2.6 does not support macos-arm64.
        Either use a newer Ruby version or use a macOS image running on amd64, e.g., macos-13 or macos-12.
        Note that GitHub changed the meaning of macos-latest from macos-12 (amd64) to macos-14 (arm64):
        https://github.blog/changelog/2024-04-01-macos-14-sonoma-is-generally-available-and-the-latest-macos-runner-image/

        If you are using a matrix of Ruby versions, a good solution is to run only < 2.6 on amd64, like so:
        matrix:
          ruby: ['2.4', '2.5', '2.6', '2.7', '3.0', '3.1', '3.2', '3.3']
          os: [ ubuntu-latest, macos-latest ]
          # CRuby < 2.6 does not support macos-arm64, so test those on amd64 instead
          exclude:
          - { os: macos-latest, ruby: '2.4' }
          - { os: macos-latest, ruby: '2.5' }
          include:
          - { os: macos-13, ruby: '2.4' }
          - { os: macos-13, ruby: '2.5' }

        But of course you should consider dropping support for these long-EOL Rubies, which cannot even be built on recent macOS machines.

The failing JRuby test has a warning note, in addition to its OOM failure:

Pass '--add-opens java.base/sun.nio.ch=ALL-UNNAMED --add-opens java.base/java.io=ALL-UNNAMED' to enable.

On Windows, this didn't pan out so well, perhaps due to some sort of quoting?

After a lot of edits, I learned that all I had to do was to ask for a little memory.
