No command to trigger manual check

[real-or-random]

I could set lsp-ltex-check-frequency to "manual" but then how could I trigger a manual check? It seems there's command that invokes https://valentjn.github.io/ltex/vscode-ltex/commands.html#ltex-check-current-document .

It seems like a missing feature from our side, we will work on it! Thanks for letting us know!
