Remove project_title additions from builds and environments

## What does this MR do?

Removed soon-to-be un-needed project title additions from builds and environments.

**This MR depends on !5998, which introduces subnav to these pages. Without it we're just removing a useful link.**

## Are there points in the code the reviewer needs to double check?

@iamphill Is this right of me? One of these still exists in `projects/artifacts/browse`, I'm not sure whether to fix the issue with `project_title`, which already has some issues with its chevron, or just remove it as it will soon be redundant.

## Why was this MR needed?

Account for fixed position MR when scrolling to elements

## What does this MR do?

This MR accounts for the new merge request fixed affix bar when scrolling to an element on the MR page.

## Are there points in the code the reviewer needs to double check?

## Why was this MR needed?

The fixed MR tabs bar was not being taken into account when shifting permalink scroll targets so that they are unobscured by navigation elements.

## What are the relevant issue numbers?

Closes #24048

See merge request !7398

The AddVisibilityLevelToGroups migration introduced a visibility_level for
namespaces and specified that projects should always have a visibility level
less than or equal to their namespace. However, some invalid rows could have
been created.

This commit introduces a migration that updates the invalid rows, setting the
invalid project to have the same visibility_level as their namespaces. This
will make some projects internal or private when they would previously have
been public or internal, but this is better than silently making an internal
or private group public.

In this case comparing old_path and new_path is not enough because there
are two entires that match.
