The English version README files of the following documents are created and translated.
1. demo/README.md
2. evaluate/README.md
3. xtuner_config/README.md
4. xtuner_config/images/README.md
5. xtuner_config/ChatGLM3-6b-ft.md
There are some format problem and language expression in the Chinese version, I also adapted them.
By the way, I modified the file name of `evaluate/General evaluation.md` and `evaluate/Professional evaluation.md` since they are shown in the `xtuner_config/README.md`
