[Minor Chores] Test out GH Forms for Issues / Pull Requests, Mermaid Graph Updates

Test out GH Forms for Issues / Pull Requests
When using aws_cdk, I noticed they had a special form you fill when filling out issues. It looks nice, look at changing to that here! (Same with the "Add your +1 👍 to help us prioritize..." line, and things like that).

Also remove the custom issue template, there's a link to a blank one at the bottom.

Mermaid Graph Updates
Turns out Mermaid supports sub-graphs! It's hard to find solid docs on doing this though. But if you combine these two:

• Styling Colors: https://www.heaton.dev/2022/05/styling-mermaidjs/
• Styling Subgraphs (Check files changed): https://github.com/mermaid-js/mermaid/pull/1245/files

To include in doc re-write:

• Estimated Cost Calculator for Everything
• What the other 2 alarms do, and enabling the "up for too long" alarm specifically (it's the one that doesn't trigger by default)
  • Maybe move the FAQ alarm into it's own section, with these two?
• Split Maturity and Container-id into two different sections. (Maybe three, with config-file). Basically re-organize that section

Also, look at updating the Examples/README.md to allow linking to each param. I e maybe something like:

### Watchdog (Dict)

Info

#### Watchdog.Threshold (int)

Info
...
### Volumes[*] (list)
