goimports missing from Install/Update Tools

[rittneje]

Reopening #3677.

At the time, it was claimed that setting go.formatTool to "goimports" really caused it to format via gopls. However, the current docs dispute this.

Specifies the tool for formatting Go code. The default is default, which uses the language server gopls as formatting provider. To configure gopls's formatting, see the 'gopls.formatting' settings. When a specific tool (e.g., gofmt, goimports) is selected, the extension will run it instead.

And indeed, deleting the goimports command from ${go.toolsGopath}/bin causes it to open an error dialog.

Please fix the "Go: Install/Update Tools" dialog to also consider go.formatTool.

Yes. I'm very sorry for the confusion here.

End of 2025, we did some re-write of formatTool and lintTool execution because people find it confusing when they set formatter "x" but it is actually using "gopls".

The reason is: some of the user is developing those "tools", so when they set "tool" to "X", they expect "X" to run instead of gopls. Otherwise, they can not develop those tools.

So we changed the behavior: instead of delegating the job to gopls, just let the user wanted "binary" to do the job. Gopls should not pretend to be something it's not.

I will verify and fix this issue. Thanks for reporting.
