fix: write 2 points in example.py

[matleg]

Closes #

Proposed Changes

Create and write 2 points instead of one in the example.py file.

Previously, the second write (with the line_protocol) erased the first write (with the Point structure) as timestamps are the same. Besides, the WritePrecision.MS made the line_protocol time conversion to somewhere in February 1970 (at time of writing), instead of current date & time.

So it is proposed here to write two distinct points to improve example understanding, and remove the WritePrecision.MS when writing with line_protocol, as is done in other examples, in order to write both points at the timestamp of execution.
