Issue #, if available: #520

Description of changes:

This fixes a regex bug that used a greedy pattern ending with incorrect path resolution, as any path after a pattern would be included in the argument.

Excerpt:

@app.get("/accounts/<account_id>")
def get_account(account_id: str):
    print(f"Account ID ({account_id}) would be 123")

# Greedy regex would inject the incorrect function parameter
@app.get("/accounts/<account_id>/source_networks")
def get_account_networks(account_id: str):
    print(f"Account ID ({account_id}) would be 123/source_networks")

In this example, say we have a GET request as /accounts/123 and another as /accounts/123/source_networks, we'd have the following effect prior to this fix:

With this fix, account_id parameter would be 123 in both occasions due to word boundary not being non-greedy. This also allows an arbitrary number of dynamic route paths and static route paths.
