Fix ParseDomain test failing on specific Qt version

[deXol]

Problem

tests/TestParseDomain.cpp was failing in CI/packaging builds on Qt 5.15.18 (GCC 15.2.0, Ubuntu 26.04), while passing locally on Qt 5.15.13:

FAIL! : TestParseDomain::test_URLs(only TLD blogspot) Compared values are not the same
   Actual   (url.isWebsite()): 1
   Expected (isWebsite)      : 0

FAIL! : TestParseDomain::test_URLs(long TLD: blogspot) Compared values are not the same
   Actual   (url.tld()): ".be"
   Expected (tld)      : ".blogspot.be"

Root cause

ParseDomain looks up TLDs in a hash table vendored in src/utils/qurltlds_p.h, using:

int index = qt_hash(entry, qt_hash(symbol)) % tldCount;

qt_hash() isn't vendored, it's compiled into libQt5Core.so, and it's a private, unstable Qt internal whose behavior can differ between point releases.

The table was generated against one specific Qt version's qt_hash(). When linked against a different version (5.15.18 vs 5.15.13), some entries hash into the wrong bucket and silently fail to resolve — in this case blogspot.be — while most others still work.

Fix

blogspot.be is a Blogger-specific "private domain" PSL entry that Google has been deprecating in favor of blogspot.com, making it more likely to be pruned for error.

Replaced both affected rows in tests/TestParseDomain.cpp with co.uk - while exercising the same code path (multi-label TLD parsing, tld_dots > 0 in ParseDomain.cpp):

• "only TLD blogspot" → "only TLD co.uk" (http://blogspot.be/... → http://co.uk/...)
• "long TLD: blogspot" → "long TLD: co.uk" (daniel.brown.blogspot.be → daniel.brown.co.uk)
