1842cfe3 - [ty] Fix 'too many cycle iterations' for unions of literals (#20137)

[ty] Fix 'too many cycle iterations' for unions of literals (#20137) ## Summary Decrease the maximum number of literals in a union before we collapse to the supertype. The better fix for this will be https://github.com/astral-sh/ty/issues/957, but it is very tempting to solve this for now by simply decreasing the limit by one, to get below the salsa limit of 200. closes https://github.com/astral-sh/ty/issues/660 ## Test Plan Added a regression test that would previously lead to a "too many cycle iterations" panic.
