This commit updates the ID for form element in create_realm.html
to "create_realm" as we would need to update the error handling
for this page in further commits and we do not want to break it
for other forms using "send_confirm" as ID.
Rename the 'language-time' title to 'General'. As the 'language-time'
section no longer exists, replace the 'lang-time-settings' classname
with the 'general-settings' classname in the 'settings_display.js' file.
Updated the 'change-the-time-format.md' and 'change-your-language.md'
documentation files to reflect these changes.
To pass the puppeteer_test Replaced the 'lang-time-settings-status'
classname to 'general-settings-status' inside 'settings.test.ts' file.
Updates frontend user-facing strings with "private message" or "PM" to
use "direct message" or "DM" respectively instead.
Note that this updates translated strings as well as a few that
are not translated like search suggestions.
Updates `tools/lib/capitalization.py` for some specific strings
that are impacted by these changes, and removes "PM" and "PMs"
from checked strings.
