Update minimum Ruby version to 3.3.0 for Rails 8.2 compatibility

[Copilot]

Rails 8.2.0.alpha (main branch) now requires Ruby >= 3.3.0, causing CI failures when attempting to bundle with Ruby 3.2.x.

Changes

• activerecord-sqlserver-adapter.gemspec: Bump required_ruby_version from >= 3.2.0 to >= 3.3.0
• .github/workflows/ci.yml: Remove Ruby 3.2.9 from test matrix (now tests 3.3.9 and 3.4.7 only)
• Dockerfile.ci: Update default Ruby version from 3.2.1 to 3.3.0
• .gitignore: Add vendor/bundle to prevent accidental commits

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• api.bitbucket.org
  • Triggering command: /usr/bin/curl curl --fail --location --max-redirs 10 --connect-timeout 30 --retry-delay 2 --retry 3 -sS REDACTED (dns block)
• https://api.github.com/repos/rvm/rvm/tags
  • Triggering command: /usr/bin/curl curl --fail --location --max-redirs 10 --connect-timeout 30 --retry-delay 2 --retry 3 -sS REDACTED (http block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

Make the main branch pass all tests against the Ruby on Rails main branch.
