Fix text in terminal showing as bold when dimmed (#7491)

Fixes text in the terminal displaying as bold when it's actually just
dim. I think it was just a simple oversight because the original code
`|`'s together the BOLD and DIM_BOLD flags, which is the same as
DIM_BOLD, which is wrong because it should only be BOLD :p

Release Notes:

- Fixed #4464
