Upgrade @asyncapi/parser to version 3.4.0 as it fixes CVE-2024-21534.

Currently, all critical dependency issues have been resolved (see the GitHub bump). I wanted to take a look to address the regressions, but it was in vain as I’m not familiar with the subject. From what I’ve observed: an error message has changed (since the library can now parse multiple files) and there is an exhaustive handling of errors in the test with the invalid.yml file. I’m not sure if the errors returned pertain to mandatory fields in version 2.0.0 of the schema.
