Merge #7727

7727: Remove documentation of obsolete extend selection command r=matklad a=lnicola

Closes #7454

This is available in LSP as `textDocument/selectionRange` and no longer exists as a stand-alone command, so we shouldn't mention it in the manual because it's confusing (it doesn't appear in `package.json`).
