config: add bare aliases for "8bit", "24bit"

Without this, setting color-mode using -o required quoting
the values, and then shell-quoting the quotes themselves
(cha -o 'display-color-mode="24bit"').

Instead of more special casing in the TOML parser, we just add aliases
for these enum values that can be parsed using TOML bare string
rules. So now this works:
cha -o display.color-mode=true-color
