revise hyperlinks labled by chinese link to chinese version docs

* correct a trivial hyperlink mistake

there exists a hyperlink which goes to the wrong page but shoud go to another title within this documentation

* Update README.md

* Update Propak_6_IMU-IGM-A1_Installation_Guide.md

* committed a file into the wrong directory on June 9

This is a stupid mistake, I found that there missed one chinese version file that I committed yesterday, finally I realized that it was in the wrong directory. The fact that it isn't in the right place can cause a real problem, because all pictures can not be shown. So please merge this modification.
