feat: add support for triple dots (***) in all parts within the path string

[richrdkng]

As of currently, the triple dots (*) are only supported and replaced at the end of a path string, e.g.:
path('@/src/***') will be transpiled to path('@/src/**/*') and then processed.

Add support for triple dots in all parts within the string, e.g.: path('@/src/***.js') will be transpiled to path('@/src/**/*.js').
