$ gopls api-json | jq
{
    ...
    {
      "Command": "gc_details",
      "Title": "Toggle gc_details",
      "Doc": "gc_details controls calculation of gc annotations.\n"
    },
    ...
    {
      "Lens": "gc_details",
      "Title": "Toggle gc_details",
      "Doc": "gc_details controls calculation of gc annotations.\n"
    }
 }

Initialization still lists gc_details, so gc_details command is registered to vscode.

[Trace - 19:16:24.915 PM] Received response 'initialize - (0)' in 1ms.
Result: {
...
  "executeCommandProvider":{"commands":["generate","fill_struct","regenerate_cgo","test","tidy","undeclared_name","upgrade_dependency","vendor","extract_variable","extract_function","gc_details","generate_gopls_mod"]},
...
}

CodeLens uses gopls_gc_details

[Trace - 19:12:38.210 PM] Received response 'textDocument/codeLens - (21)' in 0ms.
Result: [{"range":{"start":{"line":0,"character":0},"end":{"line":0,"character":0}},"command":{"title":"Toggle gc annotation details","command":"gopls_gc_details","arguments":["file:///Users/hakim/hello/mypkg/mypkg.go"]}}]

Since gopls_gc_details was never registered, vscode just errors.
OTOH, vscode sends gc_details command to gopls, which results in 'no known command' error.

internal/lsp/source: be consistent about command identifiers
a5d9e45 
The primary identifier for gopls commands was changed from Command.Name
to Command.ID(), but this change was not made in the commands passed
back to the client via ExecuteCommandOptions.

Fix this, and ensure that our regtests actually check commands against
the list of supported commands that has been sent.

For golang/go#41985
