Remove max_cache_age parameter (PP-1962)

[jonathangreen]

Description

The code was doing some questionable things to add the max_cache_age parameter to URLs. In PP-1962 I found this is causing some issues. We could do some work to fix up how we include the parameter in URLs, but since we are no longer using this parameter in the CM, it doesn't seem worth including it.

Motivation and Context

Issues I was seeing with this code:

• max_cache_age would get repeatedly included creating urls like this: http://localhost:6500/admin/web/collection/GA0011%3Fmax_cache_age%3D0%26max_cache_age%3D0%26max_cache_age%3D0%26max_cache_age%3D0/book/GA0011%2FISBN%2F9780593457580/tab/lists 🤮
• Clicking the Create New List button in the admin UI would go to a URL like this http://localhost:6500/admin/web/lists/GA0011?max_cache_age=0&max_cache_age=0&max_cache_age=0&max_cache_age=0/create which isn't a routable URL so it resulted in a white screen. The URL we wanted was http://localhost:6500/admin/web/lists/GA0011/create.
• I saw a couple other weird URL generation quirks while looking at this that I didn't note down. But removing the max_cache_age stuff fixed them

It seems like we might want to do some refactoring work to how the admin UI is generating URLs in the future, but this at least solves the issues I was seeing with the work lane editor screens.
