Move browser filters to same project
Description
Move browser filters to this project. As its easier to maintain if its under the same project
Technical details
Did some changes to gitlab ci which are explained below
- The ad filters are updated weekly so we don't want to build browser everytime the schedule is run. So a rule is added to not run the browser build when the schedule runs
- The update-filters job has needs [] which means it can run concurrently with other time taking stages
