Suggestion - Use StringSliceVar

[anzboi]

Currently some commands with string array flags use StringArrayVar to declare the flag (eg: yo generate --ignore-tables). Cobra treatsStringArray flags differently from StringSlice flags and makes these flags a little more annoying to use.

# This becomes an array with 2 values ["value1,value2", "value3"]
--array-var value1,value2 --array-var value3

# This becomes an array with 3 values ["value1", "value2", "value3"]
--slice-var value1,value2 --slice-var value3

A search on this repo reveals two flags use this, neither of them can contain , in their values.

Sorry for the delay. I think yo should use StringSlice instead of StringArray. It's welcome for the PR.
