update project standards

[joelclermont]

This pulls in a bunch of changes we've made over the last year or so since we originally created this project standard.

The most notable changes:

• Replace Docker node with Volta
• Faster CI especially around Docker build times
• Replace PHP_CodeSniffer with PHPCSFixer
• Upgrade to PHP 10 and Laravel 10
• Replace Bugsnag with Sentry
• added strict model behavior for testing

This might be a good one to review commit by commit since all the coding standard tweaks are in a single commit.

I'm having second thoughts on using the Oracle mysql/mysql-server Docker images. They seem really stale (over a year old, and stuck on 8.0.32). Meanwhile, the Docker-provided mysql images are fully up to date, even has 8.2.0 pre-release stuff, and supports arm architecture now. Should we flip it back?

@aaronsaray this is ready for review. I swapped out the Docker mysql image like we discussed
