settings: Add automatic theme detection feature. 

With this implementation of the feature of the automatic theme
detection, we make the following changes in the backend, frontend and
documentation.

This replaces the previous night_mode boolean with an enum, with the
default value being to use the prefers-color-scheme feature of the
operating system to determine which theme to use.

Fixes: #14451.

# Night mode
By default, Zulip has a white background. Zulip also provides a
"night mode", which is great for working in a dark space.
Zulip provides both a light theme and a night theme, which is great
for working in a dark space.
### Enable night mode
## Manage color theme
{start_tabs}
{settings_tab|display-settings}
2. Under **Display settings**, select **Night mode**.
2. Under **Display settings**, configure **Color scheme**.
{end_tabs}
.
The default is **Automatic**, which detects which theme to use based
on the color scheme used by your operating system.
You can also specifc **Night mode** or **Day mode** if you'd like
Zulip to use the same color scheme regardless of your operating system
configuration.
