[Documentation] Include local copy of Docs/important instructional readmes within installer

### **Proposal:** Include local copies of files in docs, as well as primary README.md. ### **Reasoning:** As a low level user, I often have to consult documentation, and have found the inbuilt Ollama apps help section to be lacking at times. As such I believe the addition of the pertinent files in the docs folder as well as the primary README could be added through the installer, and a new `ollama help` command could be added, like `ollama help documentation`. This would also allow users who have previously set up ollama, but currently have no internet a way to refresh themselves on functionality. This suggestion was thought of to help facilitate Nielson's Usability Heuristic 10, Help and Documentation, as providing the documentation with access within the app would better help users to understand how to complete their tasks regardless of circumstances(lack of internet/personal note-keeping). This could also help to facilitate heuristic 9, "Help Users Recognize, Diagnose, and Recover from Errors". For example, when an incorrect model name is entered it only states "Error: pull model manifest: file does not exist", whereas with the inclusion of the documentation files, it can guide users to the list of models(which also includes the webpage link) within the README.md file, which would help users to diagnose/recover from errors.
