[good-first-issue] Respond to commands only when mentioned

[DelusionalOptimist]

Summary Right now the bot responds to any command followed by /. This may create conflicts if there are multiple bots in the group and a given command is not meant for this bot. So the bot should respond only when it is addressed. E.g: /command@bot_name

Implementation A possible way to implement this is using regular expressions. We can add regex filters in CommandHandlers. https://github.com/JIITODC/bot/blob/22302be3e738a49ec22da6be882a50f16376a292/bot.py#L54 Here is a brief documentation on the regex filter that the python-telegram-bot api wrapper provides: https://python-telegram-bot.readthedocs.io/en/stable/telegram.ext.filters.html#telegram.ext.filters.Filters.regex

Lastly, a little guide on regular expressions: https://medium.com/factory-mind/regex-tutorial-a-simple-cheatsheet-by-examples-649dc1c3f285
