extension: Remove tooltip_text from SlashCommandManifestEntry (#1…

…6306)

This PR removes the `tooltip_text` field from
`SlashCommandManifestEntry`s.

The `tooltip_text` is currently only used to set the `menu_text` on a
slash command, which is only used for featured slash commands.

Since slash commands from extensions are not currently able to be
featured, we don't need extension authors to provide this field in the
manifest.

This is a backwards-compatible change.

 Each slash command may define the following properties:
 
 - `description`: A description of the slash command that will be shown when completing available commands.
 - `requires_argument`: Indicates whether a slash command requires at least one argument to run.
-- `tooltip_text`: Currently unused.
