Rename: change the SyntaxShape of -c flag from list to record (#10526)
# Description
Fixes: #7085 
Also closes: #7526 

# User-Facing Changes
After this change, we need to use `-c` flag like this:
```nushell
[[a, b, c]; [1, 2, 3]] | rename -c { a: ham }
```
But we can rename many columns easily, here is another example:
```nushell
[[a, b, c]; [1, 2, 3]] | rename -c { a: ham, b: ham2 }
```
