Swag ignores package path if it starts with vendor

[syed-shah-zepto]

Describe the bug
I was running swag in my package -> vendor-service. But due to a vendor prefix check, all the files are being ignored and swagger docs are not generated.

To Reproduce
Steps to reproduce the behavior:

1. Create a package with starts with "vendor"
2. Add an API and swagger annotation to that API
3. Run swag init
4. Check docs/swagger.json does not have the swagger documentation data

Expected behavior
Swagger documentation should get generated similar to packages that don't start with "vendor"

Your swag version
v1.16.3

Your go version
1.21.6

As info.PackagePath will always have the prefix of the package where swag was run, do we need this check?
If we do can we restrict it to vendor/ paths?

Would be happy to raise a PR to get this fixed.
