Don't require --force if --inline is specified.

Observe this output:

C:> Sarif.Multitool transform --inline test.sarif
The output file 'test.sarif' already exists. Use --force to overwrite.

Since --inline means "overwrite the input file", there's no reason to require force. In my recent work on #1340 I found that some commands do work in the expected way, so this is just another example of non-uniformity among the Multitool command implementations. #1631 is another example.
