Add editBotCommands for PATCH /me/commands, deprecate editBotInfo

The API no longer accepts PATCH /me: it answers "Path /me is not
recognized", so editBotInfo() fails, including for commands. Commands
now have their own endpoint, PATCH /me/commands (editMyCommands in the
official schema); bot name, description and photo are edited on the
MAX partner platform.

- Api::editBotCommands(BotCommand[]): BotCommandsInfo
- BotCommandsInfo model and ModelFactory::createBotCommandsInfo()
- editBotInfo() and BotPatch marked @deprecated
- README coverage map and docs updated
