Change url for grant detail pages

[ClaireValdivia]

Why is this issue important?

Want to implement hierarchical url structure for added discoverability

Current State

grant detail pages are following "grant/:id"

Expected State

grant detail pages should be "grants/:id"

Implementation Plan

1. Update the path in our router definition from /grant/:id to /grants/:id
2. Update the three points in the code that route to the grant detail page (https://github.com/search?q=repo%3Ausdigitalresponse%2Fusdr-gost+grant%2F%24%7Bitem.grant_id%7D&type=code)
   • We should update these to use named routes ({name: 'grantDetail', params: {id: item.grant_id}}) instead of building route strings (grant/${item.grant_id}) to make them less brittle to changes like this, easier to type in the future, etc.
3. The in-flight (Update emails to point to new Grant Details page #2705) email updates will need to link to the new URL.
