feat: make .github actions a generic example

[dtbuchholz]

Summary

The .github actions should be generic since this is a template, but they were specific to Tableland's core team (code owners, secrets, etc.). E.g., someone cloning and try to use this repo would be setting up things they don't need. This removes most of these actions and keeps generic ones.

Details

Removed unneeded .github workflows and moved the useful ones for this use case to a .github.example folder.

@awmuncy i'm assuming that since i removed GH actions, the lint/test workflows aren't running, which is blocking the merge. i'm guessing that would require an admin to merge it or something like that?

Oh, yes, you're correct. I've run into this issue before when update github actions. I'm not an admin. @joewagner can you take a look?

I'm not an admin either. Maybe @carsonfarmer is?
