Log Message:
Update to 2.4.0. From the changelog:

- As an alternative to the environment variables, you can configure the
  mob tool with a `.mob` file in your home directory. For an example
  have a look at `mob-configuration-example` file.
- As an alternative to the environment variables, you can configure the
  mob tool with a `.mob` file in your git project root directory. The
  configuration options `MOB_VOICE_COMMAND`, `MOB_VOICE_MESSAGE`,
  `MOB_NOTIFY_COMMAND`, and `MOB_NOTIFY_MESSAGE` are disabled for the
  project specific configuration to prevent bash injection attacks.
  Thanks to @vrpntngr & @hollesse making this release possible as part
  of the @INNOQ Hands-On Event, February 2022.
