Mute invisible character in one theme

[MJohnson459]

Related: #5592

Coming from vscode, the first thing I noticed (after the amazing speed that zed started) was the boldness of the whitespace characters.

This mutes the whitespace "invisible" character color in the one theme so that they are less aggressive. This more closely (but not perfectly) aligns with the one theme for vscode. In order to avoid adding a new color to the theme, I reused the editor.line_number value in both cases which worked well.

Dark

original:

editor.line_number #4e5a5f

border.variant (alternative) #363c46ff

Light

original

editor.line_number #b4b4bb

Release Notes:

• Improved: Muted the invisible character color in the one themes.
