Regenerate PKGBUILD schema

[lahwaacz]

I was trying to regenerate the PKGBUILD schema but failed due to a couple of issues:

• It seems that the keywords are extracted from the PKGBUILD man page through the lsp_tree_sitter.misc module. However, it uses the platformdirs package and its site_data_path("man") function, which gives /usr/local/share/man on Arch Linux. However, the true location is /usr/share/man.
• The init_schema function tries to read licenses from /usr/share/licenses/common:

  termux-language-server/src/termux_language_server/misc/pkgbuild.py

  Line 212 in 9cab023

  + os.listdir("/usr/share/licenses/common")

  
  This directory does not exist anymore on Arch Linux so it fails with FileNotFoundError: [Errno 2] No such file or directory: '/usr/share/licenses/common'

Also note that the schema contains several invalid fields:

termux-language-server/src/termux_language_server/assets/json/PKGBUILD.json

Lines 885 to 896 in 9cab023

	"directory": {
	"description": "(optional) Specifies an alternate directory name for makepkg to download the VCS source into.",
	"type": "string"
	},
	"fragment": {
	"description": "(optional) Allows specifying a revision number or branch for makepkg to checkout from the VCS. A fragment has the form type=value, for example to checkout a given revision the source line would be source=(url#revision=123). The available types depends on the VCS being used:\n**bzr**\nrevision (see bzr help revisionspec for details)",
	"type": "string"
	},
	"query": {
	"description": "(optional) Allows specifying whether a VCS checkout should be checked for PGP-signed revisions. The source line should have the format source=(url#fragment?signed) or source=(url?signed#fragment). Currently only supported by Git.",
	"type": "string"
	},

These come from the USING VCS SOURCES section in the man page which describes the format of specific source items. However, the lsp treats them as global variables at the same level as e.g. pkgname and pkgver.

Another outdated thing: the PKGBUILD.json schema allows custom:.+ in the license field, but not the SPDX alternative LicenseRef-.+.

termux-language-server/src/termux_language_server/assets/json/PKGBUILD.json

Lines 672 to 675 in 9cab023

	{
	"type": "string",
	"pattern": "custom:.+"
	}
