libminpack: fix broken link on spdx license

[luau-project]

Description

The current PKGBUILD for mingw-w64-libminpack has an invalid identifier for spdx license. As such, the webpage for the library points to a link that does not exist.

How

If I understood correctly how spdx licenses work on PKGBUILD, the term that comes after 'spdx:' seems to be the Short Identifier as defined by spdx website.

Thus, in this PR, I replaced the old license value (license=('spdx:BSD-4-Clause-Modified')) with license=('spdx:Minpack') on PKGBUILD. In the new behavior, it should point to Minpack License on SPDX and fix the problem.

[!NOTE]

Since this fix does not change binaries, I didn't increase pkgrel field on PKGBUILD. I don't know the MSYS2 position on this subject, so the reviewer can take that action in the proper manner.

Actual behavior

Expected behavior after the fix

According to SPDX page, the minpack license in not a free software license. Should the package be removed?

[ognevny]

the license will be changed only after rebuild. so, please, bump pkgrel

I'm not sure, but I think this package is on debian repositories for so long that I don't see a real problem. It seems, like the old value had, a BSD-4-Clause with minor modifications. Anyway, it is up to MSYS2 folks to discuss and take the best road.

Done.
