### Description

One of the easiest dimension formulas is for the dimension of `S_2(Gamma(p))`

. However, in Sage, computing this dimension is shockingly slow. For example,

sage: time Gamma(7).dimension_cusp_forms() 3 Time: CPU 17.27 s, Wall: 17.30 s sage: time dimension_cusp_forms(Gamma(7),2) 3 Time: CPU 17.22 s, Wall: 17.25 s

Fix this.

I'm setting this to "positive review" to bring it to the attention of the release manager. Release manager: please close as fixed once #11601 is merged.

This is fixed by #10546. With #10546 installed,

So I propose we close this ticket.
