When releasing a version of imodel-transformer that depends on itwinjs 5.0

Some changes to react to from core: iTwin/itwinjs-core#7512

Be sure to update dependency on @itwin/imodel-transformer in example-code/snippets of itwinjs-core https://github.com/iTwin/itwinjs-core/blob/6ced42f17813389b970aa962903dd826131350e9/example-code/snippets/package.json#L33

#225

It's kinda unfortunate to have tests and example code in itwinjs-core repo that depend on imodel-transformer package.

agree, talking to ben about what we can do wrt to example code snippets / learning section in docs from transformer repo only

[nick4598]

https://github.com/iTwin/imodel-transformer/pull/228/files initial PR to move the code snippets over to this repo.

Might stay open for a bit as we still need to look at the 'learning' section and how that works when adding to it from transformer repo. (So that we can safely remove from the learning/transformer section in the core repo, which is the one that originally referenced these code snippets)
