Implement pagination with link headers for Adoptium based apis (#1014)

* Use Link headers for Adoptium pagination

* Fix nullable pagination URL types and rebuild dist

* Add 1000-page safeguard for JetBrains pagination

* Adjust plan for pagination safeguard scope

* Move pagination safeguard to non-JetBrains installers

* Add 1000-page safeguard to Adopt Temurin and Semeru pagination

* Fix Prettier formatting in adopt, semeru, and temurin installer files

* Fix CI audit failure by updating vulnerable transitive deps

* Address PR review: RFC-compliant Link parsing, SSRF validation, centralized constant

- Make getNextPageUrlFromLinkHeader RFC 8288 compliant by splitting
  link-values and checking for rel=next anywhere in the parameters,
  not just as the first parameter after the semicolon.
- Add validatePaginationUrl utility to reject pagination URLs that
  point to unexpected origins (SSRF mitigation).
- Centralize MAX_PAGINATION_PAGES in util.ts instead of duplicating
  across Adopt, Semeru, and Temurin installers.
- Add tests for rel not being the first parameter, and for URL
  origin validation.

* Address code review feedback on pagination implementation

- Tighten rel regex with word boundary to prevent false positives
  (e.g., rel="nextsomething" no longer matches).
- Use parsed.origin comparison in validatePaginationUrl to correctly
  handle explicit default ports (e.g., :443 for HTTPS).
- Fix pagination safeguard tests to use same-origin URLs so they
  actually exercise the 1000-page limit instead of being rejected
  by origin validation on the first request.
- Add test for rel="nextsomething" not matching.
- Add test for explicit default port acceptance.

* Fix prettier formatting in util.test.ts

* Rebuild dist/ to fix check-dist CI failure
