ci: bump install-with-cpm to @v2 so old Perls install deps#48
Merged
Conversation
The Modernize CI commit (db41601) pinned perl-actions/install-with-cpm@v1 (an April 2024 tag). With its default version: main, that tag downloads the latest cpm, which since cpm v0.999.0 requires Perl >= 5.24 (the "Lyon Amendment"). So the Install Dependencies step failed before tests ran on every Perl <= 5.22: Perl v5.24.0 required--this is only v5.22.4, stopped at cpm line 2. Upstream already fixed this in install-with-cpm v2.4 (PR perl-actions/ install-with-cpm#96): when version resolves to main, no checksum is set, and the perl is < 5.24, the action auto-substitutes cpm 0.998003 (the last pre-Lyon release); modern Perls keep getting the latest cpm. Bump all five Install Dependencies steps to @v2 to consume that fix. This restores the 5.8-5.22 matrix without freezing modern Perls onto an old cpm.

Problem
CI fails on every Perl ≤ 5.22 (5.8, 5.10, 5.12, 5.14, 5.16, 5.18, 5.20, 5.22) — a clean boundary at 5.24.
MIN_PERL_VERSIONis5.008and the matrix testssince-perl: 5.8, so 5.22 is just the highest failing version, not a configured limit.The failure is in the Install Dependencies step, not the tests. Commit
