Show the entire cache entry key at hover

The key of cache entry can’t be fully displayed in the interface at<project_id>/settings/builds

But the hierarchy structured name of those keys makes the end of their name important, fi:
gradle-{{ .OS }}-{{ .Workflow }}-{{ getenv “WEEK” }}-{{ .Branch }}

Showing the entire key at hover would be very useful to be able to easily delete the relevant entries.
