Localization fixes

Description

Case 1

Original report: https://community-release.mattermost.com/core/pl/7rk7eb3i9pyajxj5sym88ugz3r

`.search_bar.usage.tips`

  • Use *on:* to find posts on a specific date\n

  • Use *before:* to find posts before a specific date\n

  • Use *after:* to find posts after a specific date\n

  • Use *dash* "-" to exclude search terms and modifiers

Add the date format (YYYY-MM-DD) to these tips for users entering the date via keyboard. There is a date picker but the date format breaks with the localization. For example, ``DD.MM.YYYY`` is used in Germany.

Case 2

The month in the date picker is not localized.

Case 3

Original report: https://community-release.mattermost.com/core/pl/obt3izr3gjbwmfq938rwyq3fyh

Observed: In `.mobile.failed_network_action.shortDescription Messages will load when you have an internet connection or {refresh}`

"refresh" could mean anything so that the sentence could differ in terms of translations. Please specify the "refresh" statement instead of using a placeholder.

Case 4

Original report: https://community-release.mattermost.com/core/pl/mi1xzgyuifyodjykw3n6nczt5a

Observed: Plural form is missing here - `.mobile.post_textbox.entire_channel.message``By using all or channel you are about to send notifications to {totalMembers} people. Are you sure you want to do this?`.

Expected: `By using all or channel you are about to send notifications to {totalMembers, number} {totalMembers, plural, one {people} other {people}}. Are you sure you want to do this?`

Could be useful for others as the word "people" varies depending on the number (singular vs plural).
