Thanks for noticing link inconsistencies and fix!
We are in the process of changing such links to sources to the API doc, e.g. https://pkg.go.dev/github.com/influxdata/influxdb-client-go/v2@v2.2.0/api/write#Point
I can merge your fix and change it after, or would you like to change that in this PR?
