Adjusts the module information collection step to be done once and in a memoized way (and at the same time build a map of reverse dependencies). This has the upside that it ~halfs the total build time for all static pages combined, but slows down loading an individual page in the dev-server.
Adds a section that shows the dependent modules for a module
Has the same "Show all" logic like the versions list if there are more than 5 entries
This currently just plainly shows the module name of the dependent crate. In the future, we may want to track which version the latest version of the dependant crate depends on (to gauge ecosystem upgrade status)
