Consider supporting prefix wildcard characters in WAOA "paths" field

[prarthana-s]

The web-app-origin-association file's "paths" field currently only supports wildcard characters at the end of the path. For example:

"paths":["/"]
"paths":["/documents/"]

However, if I specify a path such as ["*/news"], this is unsupported as the wildcard character is not at the end of the path.

Can you please consider supporting wildcard characters at the beginning of paths too? This will be useful for applications whose paths may be dynamic with data such as an identifier/username/location but have a common suffix path. For example, "/usa/news" and "/uk/news", which can be specified as ["*/news"].

I think this is a good idea that will not negatively impact performance (both prefixes and suffixes are easy to match). Developers should have more flexibility in syntax to define the set of paths to include or exclude.
I'll open a PR shortly to address this.
