[Task] Adjust documentation to avoid users naming files "Shared*"

[chris-volk]

Is your task related to a problem? Please describe.
Due to the notion of "SharedModel" and SharedModel.ttl (in the screenshot) on https://eclipse-esmf.github.io/ame-guide/modeling/shared-models.html , it can happen that projects call their files SharedModel.ttl.
This is an anti pattern, files should be named to be intention revealing for their semantic.

Describe the solution you'd like
Adjust Aspect Model Editor and its documentation screenshot, text, title, filename etc to remove "Shared".
There Are Aspect Model files with and without Aspect(s), see https://github.com/eclipse-esmf/esmf-semantic-aspect-meta-model/blob/main/documentation/decisions/0007-model-resolution.md .
