expose current file when encountering validation error

[alkalinecoffee]

The output from any errors that occur during validation do not include the file causing the failure.

This PR wraps the validation logic into a larger try block so that the failing file name is clearly displayed.

Before:

 ✓  OpenRPC & Firebolt: Lifecycle is valid
 ✓  OpenRPC & Firebolt: Localization is valid
file:///Users/jmarti350/src/firebolt-apis/node_modules/@firebolt-js/openrpc/src/validate/index.mjs:208
                                                                "value": method.result.schema
                                                                                       ^

After:

 ✓  OpenRPC & Firebolt: Lifecycle is valid
 ✓  OpenRPC & Firebolt: Localization is valid
 ✗  Error parsing /media_info.json

                                                                                           ^
