link to "sha-frontend-application" not applicable to Shesha

[MarshallRJ]

Fundamentals->app-settings.md Contains the following paragraph:

Note: client-specific settings are handled automatically and you can use the same methods GetValueAsync and SetValueAsync for reading and writing. Shesha recognizes a current application automatically using the sha-frontend-application, see details here

I think this note should be shortened and not include the reference and link to the sha-frontend-application.

eg:
Note: client-specific settings are handled automatically and you can use the same methods GetValueAsync and SetValueAsync for reading and writing.

I can make the edit if this change is acceptable.
