internal/lsp: fix query cmd usage
`query` usage has the following duplicated description.
```
Usage: query [flags] query [flags] <mode> <mode args>
```
```
$ gopls query
query: query must be supplied a mode
answer queries about go source code
Usage: query [flags] query [flags] <mode> <mode args>
The mode argument determines the query to perform:
definition : show declaration of selected identifier
query flags are:
-emulate string
compatibility mode, causes gopls to emulate another tool.
values depend on the operation being performed
-json
emit output in JSON format
```
