This is certainly a pattern we would like to avoid. For now I just went with the most straightforward transition possible to preserve behavior, but at some point we should rethink this

(#915) As this fixes a typo clearly visible in the source code, I have not added any code to reproduce the error nor a unit test. Hope this is still fine (I'm short on time currently, sorry!). See [Issue 914](#914) and/or the original pull request #590 that introduced this bug. Co-authored-by: Ioannis Tziakos <ioannist@enthought.com>

This PR starts replacing the dynamic uses of on_trait_change with observe equivalents
I am going to arbitrarily stop here to keep this PR shorter to review. After these changes, there are 18 files left containing
.on_trait_changewhich can be addressed in a separate PR.
