Go mod update from v1 to v2 results in incorrect double version suffix in URL

[ViRb3]

What Renovate type, platform and version are you using?

Test A

• Self-hosted Renovate 24.38.4
• Gitea 1.13.2

Test B

• Public Renovate Github Bot

Describe the bug

I have a Go module repo that, in its Go.mod file, references:

github.com/gofiber/fiber v1.14.6

The latest version of fiber is v2.4.1. When Renovate sends a PR, it looks like this:

github.com/gofiber/fiber/v2/v2@v2.4.1

Notice the double /v2/v2 suffix. This is wrong, and the PR fails. It should be just one /v2 instead.

Relevant debug logs

Have you created a minimal reproduction repository?

Yes. It can be found here and the bad PR is here.

@rarkins I just received a PR from the Renovate bot with a rather strange change:

https://github.com/ViRb3/renovate-bug-mrr/pull/4/files

-require github.com/gofiber/fiber v1.14.6
+require (
+	github.com/gofiber/fiber v1.14.6
+	github.com/gofiber/fiber/v2 v2.6.0
+)

v2 should have replaced v1 in the requires. Is this a regression?

[rarkins]

Please file a fresh bug report and we'll decide if we need to roll it back. Looks like go added back v1 after Renovate changed it directly
