Display Git commit ID in output of `odo` commands where the version is shown

[rm3l]

What type of PR is this: /kind task

What does this PR do / why we need it: To help with troubleshooting, this PR appends the Git commit ID next to the odo version in the output of commands where the version is shown. This currently includes:

• odo version
• odo init
• odo dev
• odo deploy

Furthermore, the Git commit ID displayed is enriched with the current state of the working tree, like -dirty if the working tree has local changes. This will help quickly understand the version and help troubleshoot commands that run in CI for example.

Example:

Before	With the changes here
``` $ asdf exec odo deploy __ / \__ Running the application in Deploy mode using my-nodejs-app Devfile \__/ \ Namespace: default / \__/ odo version: v3.14.0 \__/ ```	``` $ odo deploy __ / \__ Running the application in Deploy mode using the "my-nodejs-app" Devfile \__/ \ Namespace: default / \__/ odo version: v3.14.0 (6721c668b-dirty) \__/ ```

Which issue(s) this PR fixes: Fixes #6131

PR acceptance criteria:

• [ ] Unit test

In CI, we can see that the working tree has local changes, which is weird to me. I'm looking into this..

  [odo]   __
  [odo]  /  \__     Initializing a new component
  [odo]  \__/  \    
  [odo]  /  \__/    odo version: v3.14.0 (6721c668b-dirty)
  [odo]  \__/
  [odo] 
  [odo]  •  Downloading devfile "go:latest"  ...
  [odo] I0906 09:05:22.048551   11880 registry.go:5

Ok, the problem is that after cloning odo in CI, we are copying the local repo of odo to a temporary directory before running the tests. For the repo in the temporary directory not to be marked as dirty, the Git index needs to be refreshed (either manually or using other Git commands that can auto-refresh it), but that should not be an issue for the doc automation tests here. 3c06ce0 (#7074) just ignores the Git commit ID when comparing the outputs.
