Bump appraisal-rb/setup-ruby-flash from 2.6 to 2.12

[dependabot]

Bumps appraisal-rb/setup-ruby-flash from 2.6 to 2.12.

Release notes

Sourced from appraisal-rb/setup-ruby-flash's releases.

Release v2.12

Configure Rust builds for the GNU ABI used by Windows RubyInstaller so rb-sys extensions no longer target MSVC.

Release v2.11

Fix Windows native extension recovery when rv leaves compiled extensions under malformed staged paths without their Makefile. Recovery now derives the install destination from the staged path and supports extensions installed at the lib root.

Release v2.10

Fix Windows native extension recovery for CRLF-generated Makefiles. The recovery script now matches the JSON extension TARGET correctly and restores its compiled library before the bundle is used.

Release v2.9

Fix Windows recovery for native extensions whose compiled binaries are displaced from their build Makefiles. Recovery now matches each binary to the generated Makefile TARGET and restores it under target_prefix.

Release v2.8

Fix Windows recovery of compiled native extensions by preserving each extension's Makefile target path. This restores correct loading for nested extensions such as JSON's json/ext/generator.so.

Release v2.7

Fix rv fast-install validation. This is a workaround for this issue: spinel-coop/rv#792

After rv clean-install, the action now runs bundle check and falls back to bundle install when native extensions are missing.
