make command signature parsing more strict (#14309)
# User-Facing Changes

The parser now errors on more invalid command signatures:

```nushell
# expected parameter or flag
def foo [ bar: int: ] {}

# expected type
def foo [ bar: =  ] {}
def foo [ bar: ] {}

# expected default value
def foo [ bar = ] {}
```
