8348328: Update IANA Language Subtag Registry to Version 2025-05-15

[RadekCap]

Backport of JDK-8348328 - Update IANA Language Subtag Registry to Version 2025-05-15

The IANA Functions Operator has updated the language subtag registry to "2025-05-15".

Clean backport.
Passed tier1 tests.

GH Actions are passing

A local run exposed the same subset of failing jtreg tier1 tests and on the master branch. Those failures are unrelated:

java/foreign/nested/TestNested.java:
PaddingLayout is a preview API and is disabled by default.

compiler/escapeAnalysis/TestFindInstMemRecursion.java:
test result: Failed. Execution failed: `main' threw exception: java.awt.AWTError: Can't connect to X11 window server using ':0' as the value of the DISPLAY variable.

@RadekCap Why is this being requested as a critical fix (to go into the July release)? If at all, it should perhaps go into the October release.

[RadekCap]

@jerboaa It was my understanding from the original PR in 21u-dev - openjdk/jdk21u-dev#1846 (comment)

Based on this, I waited for 24u approval.

Based on the latest comment in 21u-dev - openjdk/jdk21u-dev#1846 (comment)

I created this PR in 21 to get it into the July release.

It's up to you, maintainers, if you would prefer a July or October release. I can do both.

I have a draft PRs in 21-udev, 17-udev, and 11-udev based on jdk approved change - openjdk/jdk#25503

Please let me know which way I should pick. Thank you.

Hi @RadekCap
I would just target the same release as Oracle does.
So we can just keep this pending until either Oracle pushes it to the July release
or the July release is delivered.
They will for sure backport it to the October update.
Best regards, Goetz.

Hi @RadekCap
