Docs: Created GH Action workflow to generate pdfs of outbound checklist from markdown files

Problem

Now that for each outbound checklist we support 2 file formats, there is an opportunity to automate the process of updating the checklists by creating a github action that generates a new pdf whenever a change has been made in the checklist markdown file.

Solution

Created a new GH Action workflow called checklistMarkdownToPDF.yml

• Triggered when a PR has been opened or updated for tier*/checklist.md files
• First job identifies which checklist.md tiers have been updated. Stores them in an array
• Second job generates newly updated pdfs for those tiers

Result

When a change has been made in tier*/checklist.md, a pdf of the updated checklist will be generated.

LGTM +1 🚢

IDEA: Let's document/pull down copies of the jobs/workflows somewhere so that we have local backups in case there are any issues upstream?

One minor issue but otherwise LGTM!
