[FIX] dx: port back js tooling gitignore properties
The tooling has been introduce in later version of odoo.
It is a problem when somebody switches to older branches without
disabling the tooling as it would then try to commit the tooling config
files.
We just add a few lines in the gitignore to prevent this issue.
