Subject: [PATCH 1/2] Minimize CI matrix to earliest and latest versions

- Ruby: 3.2 and 4.0 (was 3.2, 3.3, 3.4, 4.0)
- Rails: 7.2 and 8.1 (was 7.2, 8.0, 8.1)
- Add RAILS_VERSION env var to dynamically set Rails version
- Update actions/checkout from v3 to v6

Reduces CI runs from 12 to 4 while still testing boundary versions.

+## Version Support
+
+F(x) follows the maintenance policies of Ruby and Rails, supporting versions
+within their official maintenance windows.
+
+**Ruby:** 3.2+ ([maintenance branches])
+
+**Rails:** 7.2, 8.0, 8.1 ([maintenance policy])
+
+When a Ruby or Rails version reaches end-of-life, support will be dropped in the
+next minor release of F(x). Older versions may continue to work but are not
+tested or guaranteed.
