Switch to schema versioning

[jinnatar]

Neuter the precommit hook, fix current dev schema at version 3

• Roll all current schema changes into schema version 2
• dev branch is now tracking schema version 3
• Drop FUNDING.yml, no active maintainer was on it
• Switch docker image versioning scheme to include commit hash

This leaves an open issue where pokedex updates don't happen automatically again but that will be fixed in an upcoming change that makes it available in many ways that can be automated instead of built-in automation since we're losing the source of triggering it on changes.
