Rohan Challa 46bd65c853 internal/lsp/cache: add concurrency error check for go cmds
This change attempts to fix a concurrency error that would cause
textDocument/CodeLens, textDocument/Formatting, textDocument/DocumentLink,
and textDocument/Hover from failing on go.mod files.

The issue was that the go command would return a potential concurrency
error since the ModHandle and the ModTidyHandle are both using the
temporary go.mod file.

Updates golang/go#37824
