The dependabot configuration contained some number of ignored versions
that date from when GitHub dependabot support was added. These versions
fall into three categories:
- Versions that are older or the same version as the version we use.
- Versions that are newer than the versions we use.
- Versions for crates we no longer depend on.
This change removes all ignored versions and updates dependencies in
the second category.
Most tests were only being run for layout-2013, not for layout-2020.
This wasn't great since layout-2020 is now the default.
So this patch unifies the lists of included tests for both layouts.
For layout-2013 this implies adding css/css-content/, css/css-logical/
and css/css-masking/clip/.
For layout-2020 this implies adding several additional css tests, and
also tests like dom/, js/, html/, etc.
