- this commit bumps `eslint-plugin-ghost`, which bumps compatiblity to
2022
- this also removes a lot of the manually-added
`parserOptions.ecmaVersion` that we had in imported packages, in favor
of the value set in `eslint-plugin-ghost`

- @babel/eslint-parser was added to enable support for static members on classes but this causes other problems as it fails on eslint ugprades etc
- a better solution is to set ecmaVersion to 2022, as our default is 2018 which does not support static, yet 2022 does
