* gnu/packages/golang.scm (gofumpt): Update to 0.7.0.
[source] <snippet>: Remove it and re-implement the logic in the
'set-fallback-version phase,  #:build-flags and #:test-flags.
[arguments] <go>: Use go-1.22.
<build-flags>: Provide version.
<test-flags>: Skip one test.
<phases>: Add 'set-fallback-version.
[propagated-inputs]: Remove go-github-com-pkg-diff, go-github-com-kr-text,
go-github-com-kr-pretty, and go-github-com-frankban-quicktest.
[native-inputs]: Remove go-gopkg-in-errgo-v2; add go-github-com-go-quicktest-qt.
