test: ignore asan new_delete_type_mismatch

This commit adds ignore for new_delete_type_mismatch in EnvironmentTest
as this is currently generating an error when address sanitizer is
enabled and gcc is used as the compiler.

This might be a little risky as we run the risk of missing other errors
of this same type but I'm still looking into if this could be solved in
some other way in V8 and perhaps this could be a short term fix.

Fixes: nodejs#35669
