[x] Move all Espree-specific files into packages/espree
[x] Update release-please configuration to be a monorepo setup (like `eslint/rewrite)
[x] Update root README so it's not Espree-specific
Additional information
This PR provides initial monorepo setup & moves espree to packages/espree. I'll create separate PRs to move rest of the packages to this repo. There are already too many files changed that the GitHub UI lags when going through file changes. Or do we want to move all the packages in one PR?
Not publishing espree to JSR, like other packages in the rewrite repo.
