Toolbars: Fall back to name if both title and icon are not specified

[huyenltnguyen]

Issue: #15259

What I did

• Fixed a regression by setting name as the fallback for toolbar title if both icon and title are not specified in globalTypes. I also added a warning to the console to let the users know how to update their code.
• Added a warning to the console in the case where showName is set to true. This is related to this change where we deprecated the showName config.

How to test

• Is this testable with Jest or Chromatic screenshots?
• Does this need a new example in the kitchen sink apps?
• Does this need an update to the documentation?

Tested with examples/cra-ts-essentials.

@huyenltnguyen could you update this PR? I would do it, but I don't have authorization to commit to your fork.

Please merge in the base branch next, so that the CI runs and checks if everything is still compatible.

@yannbf could you review as well?

Chromatic borked for a second but I updated the branch and it's all good now. Seems like a great change. Thank you so much for that @huyenltnguyen !
