filename-case: add $ as an ignored char

[ruiaraujo012]

Description

I'm working with tanstack router and the route params are defined with $, like $userId.tsx, but this rule doesn't ignore this char. I saw that it was an ignored char in the past, can you put it again?

Fail

src/app/routes/_area-reservada/area-reservada/certidoes/$idCertidao.tsx

Filename is not in kebab case or pascal case. Rename it to $id-certidao.tsx or $IdCertidao.tsx unicorn/filename-case

Pass

src/app/routes/_area-reservada/area-reservada/certidoes.tsx
