Follow-up: Remove dynamic QA selectors from audit logs template and make them generic

The new audit logs template and corresponding Vue app allowing the implementor to customise the QA selectors being used for the filters and the table.

This comes from the older system this template was/is replacing, where the system had unique QA selectors for each audit log page (Admin, Group and Project).

We can replace this with a more generic QA selector implementation and update the QA tests accordingly.

Suggested values:

filterQaSelector - audit_log_filter
tableQaSelector - audit_log_table
