Valid paths not matched from serverless.yml

[DanRVP]

With a HttpAPI definition like so:

functions:
    my_function:
        name: my-function
        handler: handler.php
        description: ''
        runtime: php-83
        events:
            - httpApi: 'ANY /{param}'

The error 404 - Route '/myroute' not found in serverless.yml is returned.

This issue lies in Router::fromServerlessConfig() and Router::matchesMethod().

1. fromServerlessConfig only does extra parsing on array definitions via patternToString. In this case only a lower-case any is converted to *. Uppercase ANY is always skipped. No extra checks are done on strings.
2. matchesMethod will only look for *, assuming that the upstream call to fromServerlessConfig has correctly parsed and converted ANY to a wildcard.

In both cases a valid API gateway definition is skipped.
