config: allow using bright but not bold text when brightening text
In https://github.com/wez/wezterm/issues/2932 the user desired to have brightened text without the boldness, as they were accustomed to that behavior in a couple of other terminal emulators. This commit changes the `bold_brightens_ansi_colors` from a simple boolean to a tristate that allows for not changing the brightness, changing the brightness, and changing the brightness while adjusting the boldness down to normal levels. boolean values are accepted for backwards compatibility.

assumes that Black+Bold renders as a Dark Grey which is

false, it would render as Black on Black.
|

|

*Since: nightly builds only*
|

|
||||
This option can now have one of three values:
|
||||
|
||||
* `"No"` - the bold attribute will not influence palette selection
|
||||
* `"BrightAndBold"` - the bold attribute will select a bright version of palette indices 0-7 and preserve the bold attribute on the text, using both a bold font and a brighter color
|
||||
* `"BrightOnly"` - the bold attribute will select a bright version of palette indices 0-7 but the intensity will be treated as normal and a non-bold font will be used for the text.
|
||||
|
||||
You may use `true` or `false` for backwards compatibility. `true` is
|
||||
equivalent to `"BrightAndBold"` and `false` is equivalent to `"No"`.
