ref(billing): Add const assertion to DATA_CATEGORY_INFO (#61652)

Use a const assertion here so that in this PR:
https://github.com/getsentry/getsentry/pull/12375 we may be able to
restrict the string literals of `.plural` to just include the plural
data category literals (`errors`, `attachments`, `monitor check-ins`,
etc...)
