Rename "Slash commands" to "Quick actions"

Fix https://gitlab.com/gitlab-org/gitlab-ce/issues/27070

Deprecate "chat commands" in favor of "slash commands"

We looked for things like:

 - `slash commmand`
 - `slash_command`
 - `slash-command`
 - `SlashCommand`

+# GitLab quick actions
+
+Quick actions are textual shortcuts for common actions on issues or merge
+requests that are usually done by clicking buttons or dropdowns in GitLab's UI.
+You can enter these commands while creating a new issue or merge request, and
+in comments. Each command should be on a separate line in order to be properly
+detected and executed. The commands are removed from the issue, merge request or
+comment body before it is saved and will not be visible to anyone else.
+
+Below is a list of all of the available commands and descriptions about what they
+do.
+
+| Command                    | Action       |
+|:---------------------------|:-------------|
