Make syntax of `@see` compatible with LuaLs

LuaLs uses `#` to split reference and description:

```lua
--- @see Foo.bar # description of `see` content.
```

while EmmyLua uses it to split type and member:

```lua
--- @see Foo#bar
```

# Considerations

In order not to break existing code, we can check whether there are spaces around `#`. Alternatively, we can drop current behavior and only use LuaLs syntax.
