[bug]: zinit compile --all operates on irrelevant files in $ZINIT[PLUGINS_DIR]

[nbrown]

Issue description

macOS creates .DS_Store files in directories opened with finder. If one is created in the zinit plugin directory, ${ZINIT[PLUGINS_DIR]}, the command zinit compile --all treats .DS_Store as a plugin. This occurs because of the following line in zinit-autoload.zsh:

2332: plugins=( "${ZINIT[PLUGINS_DIR]}"/*(DN) )

If we add / to the glob qualifiers, files in the plugin directory won't be added to the plugins variable. I quickly checked to see if this construct is used anywhere else and found a few similar constructs:

zinit-autoload.zsh
2019:        files=( ${ZINIT[PLUGINS_DIR]}/*(ND/) )
2126:    plugins=( "${ZINIT[PLUGINS_DIR]}"/*(DN) )
2332:    plugins=( "${ZINIT[PLUGINS_DIR]}"/*(DN) )
2544:    plugin_paths=( "${ZINIT[PLUGINS_DIR]}"/*(DN) )
2940:    plugins=( ${ZINIT[PLUGINS_DIR]}/*(DN-/) )

This should probably be made consistent but I am unsure if the - should be included or not. I also did not do a thorough search, so there may be others I missed.
