Track page visits to the secrets manager

What does this MR do and why?

This adds tracking functionality for the secrets manager, in both project and group contexts. This MR tracks page visits; we will iterate on the other instrumentation we need in future MRs.

To be tracked:

• Page visits
• GraphQL errors workflowin dev
• UI interactions (more to be added) workflowready for development

Page visits in the PROJECT context use the visit_project_secrets_manager action, while page visits in the GROUP context use visit_group_secrets_manager. Both categories can have the following labels based on which page is visited:

• secrets_table_page
• secret_details_page
• create_form
• edit_form
