Fix Linting Issues - 8.x-2.x-dev

Assigning this to myself to begin work on the issue, thanks!

I have completed fixing all the linting issues that were discovered by adding the gitlab-ci.yml file to the module.
I have also updated the variables in the gitlab-ci.yml file.

Moving to "Needs review" status and unassigning myself from the issue, thanks!

Moving back to needs work - eslint is failing on the MR. Cspell also failed

Just like in the 5.0.x branch...

If you look at the cspell error, it flags 'Grey' and 'grey' repeatedly.
If you look at the variables section of the gitliab-ci.yml you can see the list of words that should be ignored.
Both 'Grey' and 'grey' are on the list but the linting continues to flag it.
I am unsure of why this is happening or exactly how to fix it.

The only place eslint fails is the jQuery .ready function wrapping the JS code.
I have tried 2 different code recommendations that should clear that eslint flag but was not able to get eslint to pass successfully.
