Always pretty print binary values in table (#12294)

Browse Source 
# Description
Binary values passed to `table` may or may not be pretty formatted based
on the output destination. This leads to weird behavior as documented in
#12287. This PR changes `table` to always pretty print binary values.
However, binary values passed to external commands will not be formatted
(this is the existing behavior).

# User-Facing Changes
This is a breaking change. E.g.:
```nushell
0x[8989] | table | cat -
```
used to print raw bytes, but it will now print the pretty formatted
bytes.

# After Submitting
Add to 0.92.0 release notes and update documentation.
