fix: Search result redirect to unit lib component

[yusuf-musleh]

Description

This PR fixes redirection to the library component in the unit when selecting the search result. It also fixes an issue with navigating to the library mfe when selecting a library component.

Testing instructions

1. Run this branch on your local tutor
2. Make sure you have meilisearch configured and running in your local tutor
3. Make sure you have a Content Library with some blocks created under it, eg: text or dropdown blocks
4. Make sure you have a course that contains a library block in a Unit that includes a Content Library block from the previous step. You probably need to use the old studio UI to select the Content Library to be in the library component block in the Unit if you don't already have one set (since you cannot edit library components in the new mfe UI yet)
5. Use the search modal in the mfe to search for the library block that belongs to the library component that is inside the Unit (make sure that you are clicking on the block that is inside the unit, not the actual library component that)
6. Confirm that it will navigate to the correct unit context and highlight the library component in the unit (i.e. "Randomized Content Block")

@yusuf-musleh Looks good! 👍

• I tested this: I followed the testing instructions
• I read through the code and considered the security, stability and performance implications of the changes.
• I tested that the UI can be used with a keyboard only (tab order, keyboard controls).
• Includes tests for bugfixes and/or features added.
• Includes documentation
