fix: improve active link highlighting for edge cases

Attempt improvement by moving the scroll to anchor logic to the end of window load and adding 1 to elementOffset in case of navbar border.

Appears to solve any issues that could arise (such as when clicking Courses and then Publications, but Projects being highlighted instead) in local testing.
