fix: correct Greek September spelling (Σεπτεμβρίου)

[Koan-Bot]

What

Fixes the misspelled Greek genitive for September in Date::Language::Greek.

Why

"Σεπτεμτου" was missing the "βρί" syllable. The correct Greek genitive form is "Σεπτεμβρίου". This caused %B formatting to output an incorrect word for September in Greek.

Testing

prove -l t/ — all tests pass, including updated lang-data.t expected value.

This looks correct after checking google translate

my $month = "September";
my %en_to_gr = (
  September => "Σεπτέμβριος",
);

Greptile Summary

Fixes a long-standing typo in Date::Language::Greek where the September genitive "Σεπτεμβρίου" was stored as "Σεπτεμτου" (missing the "βρί" syllable), causing %B formatting to output a malformed word. The companion test is updated with the correct Unicode codepoint sequence, which correctly decodes to "Σεπτεμβρίου".

Confidence Score: 5/5

Safe to merge — a correct one-line spelling fix with a matching test update and no other changes.

The change is minimal and surgical: one character-sequence corrected in the data module and the corresponding Unicode codepoints updated in the test. The new codepoints decode exactly to "Σεπτεμβρίου" confirming correctness. No logic, API surface, or other languages are touched.

No files require special attention.
