[Settings] Print pretty values for settings as their converted values, rather than strings

### What was the end-user problem that led to this PR?

The problem was `bundle config` would print bool keys as strings (i.e. `true` was printed as `"true"`)

### Was was your diagnosis of the problem?

My diagnosis was we needed to convert the values before formatting them

### What is your fix for the problem, implemented in this PR?

My fix extracts the conversion method, and calls it in `pretty_values_for`
