chore: add pointer cursor on button hover for Rafiki Admin

[JoblersTune]

Changes proposed in this pull request

Since buttons and links are styled the same it felt jarring to have some activate a pointer cursor on hover while others didn't. This overrides Radix's default behaviour that buttons don't get a pointer cursor since our button and link styles are the same so it causes confusion.

Context

Override Radix's default behaviour that buttons don't get a pointer cursor.
