go: Adjust gopls path based on OS (#22727)

Based on the python #21452
and PR #22587

I found the same problem with go on windows.

Describe the bug / provide steps to reproduce it

Language server error: gopls

The system cannot find the file specified. (os error 2)
-- stderr--

[ERROR project::lsp_store] Failed to start language server "gopls": The
system cannot find the file specified. (os error 2)
[ERROR project::lsp_store] server stderr: ""

Environment

    Windows 11
    Go

Release Notes:
