Very minor nitpick/request. Not directly with this patch set but with
the category_test which is related and also recently committed.

I'm testing out "make update-unicode" scripts, and due to my system ICU
version being different from the PostgreSQL unicode version I get the
expected warnings from category_test:

Postgres Unicode Version:       15.1
ICU Unicode Version:            14.0
Skipped 5116 codepoints unassigned in ICU due to Unicode version mismatch.
category_test: All tests successful!

I know it's minor, but I saw the 5116 skipped codepoints and saw "all
tests succeeded" but I thought the output might be a little nicer if we
showed the count of tests that succeeded. For example:

Postgres Unicode Version:       15.1
ICU Unicode Version:            14.0
Skipped 5116 codepoints unassigned in ICU due to Unicode version mismatch.
category_test: All 1108996 tests successful!

It's a minor tweak to a script that I don't think even runs in the
standard build; any objections?  Patch attached.
