Add a setting to disable requirements checks

[miiimooo]

Is your feature request related to a problem? Please describe.
When running in a local dev environment then it should be possible to disable environment checks of the module so it can stay enabled.
Currently, running lando drush updb -y breaks because of the check in search_api_pantheon_requirements

This is because the default config should in my opinion reflect the production environment

Describe the solution you'd like
Add a setting that can be toggled in settings.local.php to disable the checks

Describe alternatives you've considered

1. Thought about setting the PANTHEON_INDEX_* environment variable in lando config but that gets confusing
2. Move the search api pantheon to the production split but that gives a dependency issue in the search api server config and subsequently the search api index config - module not enabled in local
