feat!: add support for parser API v3

[jonaslagoni]

Description
This PR adds support for parser API v3, as of @asyncapi/parser@3.0.0-next-major-spec.9. This means that parser API v2 support stops at @asyncapi/parser@3.0.0-next-major-spec.8.

Here are the changes introduced:

• Updated the dependency names so they match each parser API i.e. v1 -> v3
• Added tests to the converter to check that v3 can downgrade to v2 and v1
• Adapted the tests for parser to check parser API v3 works as expected
• Hardcoded parser API v2 to @asyncapi/parser@3.0.0-next-major-spec.8 as 9 introduces parser API v3
• Added parser API v3 dependency
• Adapted the implementation to to support parser API v3
