enchant2: update to 2.8.1.

2.8.1 (June 12, 2024)
---------------------

This release restores an optimization removed in 2.8.0 that reduces the
frequency with which personal wordlists are reloaded. This optimization
seemed to be unnecessary, as it had no effect on the test suite, but its
removal caused a significant slow-down for real-world use. Apologies to
those who are affected by this, and many thanks to the user who reported
this problem.
