[ruby/rubygems] Fix test suite that will start to fail whenever we attempt a release:

- ### Problem

Whenever we bump the bundler `VERSION` to a non development release,
like we recently did in [4.0.9](https://github.com/ruby/rubygems/pull/9426)

The test suite will behave differently and will break due to the
Bundler checksum feature introduced in https://github.com/ruby/rubygems/pull/9366

This is because the expectactions of tests that have a lockfile'
will sometimes include a checksum line for the bundler gem itself
depending on whether this condition evaluates to `true`.

https://github.com/ruby/rubygems/blob/34d19fa8a3f84c50e2ba65e0f39c80045e7cbfb8/bundler/lib/bundler/lockfile_generator.rb#L106

### Solution

We can modify the spec helper `checksums_section_when_enabled` to
automatically append a checksum entry for bundler whenever necesary
