struct-tag: support "properties" tag

[ccoVeille]

"properties" was added to the well-known struct tags on Go wiki

• wiki: add "properties" to well-known struct tags golang/go#72759

• Well-known-struct-tags: add properties tag golang/wiki#44

It could be added to revive to the very sane way TOML support was added recently to struct-tag rule

• feature: add support for TOML struct tags in struct-tag rule #1255

Here is the documentation of the format of this tag

https://pkg.go.dev/github.com/magiconair/properties#Properties.Decode

Based on my understanding of the code and documentation only the following options are supported

• "-" ignored
• "default" (without it a field is required)
  Note: There is a special notation using ; for slice/array default value.
• "layout" (only for time.Time type)
