fix: University tests

[kingthorin]

Extended the expected regex to include a few characters with accents.

Addresses #1404 (comment)

Add recently introduced test artifact test.txt to .gitignore

FYI if anyone needs to run single UnitTest classes or methods locally you can use:
./mvnw test -Dtest=UniversityTest
./mvnw test -Dtest=UniversityTest#testName
syntax.

PR Summary

• Creating a Constant For University Name Matching
  In the UniversityTest.java, a new constant UNIVERSITY_MATCHER was introduced. This constant is used to find and verify university names based on certain rules, making the matching process consistent and easy to manage.

• Improving the testName Method
  The testName method was adjusted to employ the newly created UNIVERSITY_MATCHER. Previously, it used a less flexible, hard-coded matching pattern, so this change should make the testName method more adaptable and efficient.

• Updating the Provider List Test Method
  The providerListTest method was changed to incorporate the UNIVERSITY_MATCHER for testing the university.place specification. This adjustment will make its testing protocol more consistent with other tests that use the same university name matching rule.

1. Why it's needed to ignore file "test.txt"? I don't see any tests that would create such a file.
2. This regex is not enough. UniversityTest still can fail:

java.lang.AssertionError: 
Expecting actual:
  "North Leffler Academy of Aix-Marseille"
to match pattern:
  "[A-Za-z'() öèü]+"

Oops thanks, I didn’t account for hyphen or other chars, I had searched non-ASCII.

I’ll dig into the test.txt thing, maybe it was something I’d polluted the repo with somehow.

[kingthorin]

@asolntsev fixed.
