gorelease changelog failes with gitea

[nickytd]

The gorelease action fails when running against a gitea instance.
The .gorelease.yml configuration snippet is minimalistic:

changelog:
  use: gitea
gitea_urls:
  api: https://gitea...../api/v1
  download: https://gitea.....
  # set to true if you use a self-signed certificate
  skip_tls_verify: true

and the output is following:

• generating changelog
