Fix release workflow (bevyengine#4903)

# Objective

While playing with the code, I found some problems in the recently merged version-bumping workflow:
- Most importantly, now that we are using `0.8.0-dev` in development, the workflow will try to bump it to `0.9.0` 😭 
- The crate filter is outdated now that we have more crates in `tools`.
- We are using `bevy@users.noreply.github.com`, but according to [Github help](https://docs.github.com/en/account-and-profile/setting-up-and-managing-your-personal-account-on-github/managing-email-preferences/setting-your-commit-email-address#about-commit-email-addresses), that email address means "old no-reply email format for the user `bevy`". It is currently not associated with any account, but I feel this is still not appropriate here.

## Solution

- Create a new workflow, `Post-release version bump`, that should be run after a release and bumps version from `0.X.0` to `0.X+1.0-dev`. Unfortunately, cargo-release doesn't have a builtin way to do this, so we need to parse and increment the version manually.
- Add the new crates in `tools` to exclusion list. Also removes the dependency version specifier from `bevy_ecs_compile_fail_tests`. It is not in the workspace so the dependency version will not get automatically updated by cargo-release.
- Change the author email to `41898282+github-actions[bot]@users.noreply.github.com`. According to the discussion [here](actions/checkout#13 (comment)) and [here](https://github.saobby.my.eu.orgmunity/t/github-actions-bot-email-address/17204/6), this is the email address associated with the github-actions bot account.
- Also add the workflows to our release checklist.

See infmagic2047#5 and infmagic2047#6 for examples of release and post-release PRs.
