Added Solr to Lando with a script to fetch the latest Solr config

[stephen-cox]

This PR adds Solr to Lando for the localgov_search_solr module.

To test it you will need to composer require localgovdrupal/localgov_search_solr and enable it.

Fixes #86

To test it you will need to composer require localgovdrupal/localgov_search_solr and enable it.

Do we want to include localgovdrupal/localgov_search_solr in the project then? So not it localgovdrupal/localgov but here?

Manual test (and maybe useful for c&p for documentation):-

## first lines probably only for testing fresh like now
$ lando rebuild # needed to get the solr container
$ lando drush si -y localgov # needed to reinstall the site

$ lando composer require localgovdrupal/localgov_search_solr # have suggested maybe we want to do this in the project

$ lando drush en localgov_search_solr # enable solr search for the site
$ lando update-solr-config # update the config
$ lando restart # reload the config

Done!

Only other note. It's adding the configuration to the directory. So anything that's already there like if the default config with English and Irish it stays there even when just English is enabled in the new export.

This works for me locally and I love it!

Thanks @stephen-cox and @ekes and @andybroomfield !
