undeclared build-time dependency on libnumbertext 1.0.6

Hi,

my LO 7.0.0 build on Debian buster failed:

[...]
Test name: SwUiWriterTest::testTdf133589
equality assertion failed
- Expected: 𐳥𐳋𐳓𐳉𐳗
- Actual  : székely 0

Failures !!!
Run: 305   Failure total: 1   Failures: 1   Errors: 0

This looks like libnumbertext needs to be 1.0.6 which does have this new
"old hungarian" feature... (yes, "of course" --with-system-libnumbertext
and libnumbertext in Debian buster is 1.0.5).

The other alternative is to do it like the DLP libraries and only do the
test needing it if libnumbertext is 1.0.6 and thus support "old
hungarian"...

Which one would you prefer? The first one of course is trivial :-)
