fix: Skip the fuzzer test for Spark regexp_instr function

[rui-mo]

The regex cache limit makes expression evaluation order-dependent. Common eval
and simplified eval process rows in different orders, so they hit the cache
limit on different rows, producing different results. This PR skips the uzzer
test for Spark regexp_instr function.

Fixes #17697.

Thanks @zhli1142015. Could you please mark ready-to-merge label for this PR? Thank you.

It looks like I lost my Collaborator permissions for some reason, though I'm not sure why. You can tag the ready-to-merge label yourself to unblock for now.

@pedroerp , could you help restore my Collaborator access? Thanks!

[rui-mo]

@zhli1142015 Thanks. Yes, the permissions may need to be restored.
