What is the current behavior?

Our prettier config misses certain files that may be worthwhile to format

GitHub Issue Number: N/A

What is the new behavior?

this pr is broken into 2 commits:

chore(repo): format .github/

68b6c0b

this commit updates our prettier configuration to format all yaml files
in the .github directory at the root of the the repo. both .yml and
.yaml were added. although the latter isn't used today, it is added as
a bit of 'future proofing'.

with the updated config, prettier was run on the repo. the only change
that is worth noting is that none of the double to single quote changes
shouldn't be of issue, as the contents of the strings themselves don't
have an double quotes in them (e.g. ""something"")

this was motivated by the fact whenever I work on CI, I know I'm always second guessing
the consistency of our files, and spacing/quotes have been called out on code reviews before.

chore(repo): format top level javascript

7c14a27

this commit updates the prettier configuration for the project to format
all top level .js files. this commit then formats those files.

motivated by #3583, I want us to have an IDE agnostic way of formatting this file

Does this introduce a breaking change?

• Yes
• No

Testing

I ran prettier with the main@HEAD and this branch, each time piping the output to a text file.
In each text file, I removed the trailing time it took to format each file (because that changes between runs) using the regex \s\d+ms to capture things like ' 123ms' and ' 0ms'
I then diffed those files, which resulted in the following:

7c7
< > prettier "./({bin,scripts,src,test}/**/*.{ts,tsx,js,jsx})|bin/stencil" "--write"
---
> > prettier "./({bin,scripts,src,test}/**/*.{ts,tsx,js,jsx})|bin/stencil|.github/(**/)?*.(yml|yaml)|*.js" "--write"

as we can see, only new files are added to our checks, and they match was the git commit messages state they check

--strictNullChecks error report

Typechecking with --strictNullChecks resulted in 2190 errors on this branch.

That's the same number of errors on main, so at least we're not creating new ones!
