Add shorthand button creation to ModalCard

[SteveMicroNova]

What does this change intend to accomplish?

This is a sister PR to #1015 and so will be merged into #1015 if this merges first, and into main if this merges second

This is not directly a part of #1015 because the amount of replumbing that this entailed seemed like any issues this causes would easily become a needle in a haystack

Only asking Klayton to review this time as he has opinions on how to React
I think that my solution is potentially gross, but is good for dynamically creating any number of buttons without needing to import new components on every page that uses the ModalCard
