Add Rails 8 compatibility

In specific:
- Do not test Rails 7.0 against 3.3
- Allow 8.0 in gemspec, by relaxing the upper constraint to `< 8.1`.
  Rails uses shifted SemVer, so `8.1` is considered a Major.
- Conditionally load the sqlite3 gem based on the Rails version.
- Conditionally load selenium webdriver gem based on the Rails version.
- Simplify error page assertions to account for variations in
  apostrophes, as "We're sorry" changed to "We`re sorry" in Rails 8.
