[enhancement/documentation] - boschsensortec/BME280_SensorAPI - adding table of contents and fine tuning documentation + minor fixes

Greetings

I just revamped the documentation of this repository by:

• adding a table of contents
• fine tuning some minor issues

besides this:

• most of the work was done by me on my own
• i used grok just for reviewing part of the code after completing my modifications

i hope that:

• you feel free to draw some feedback. i understand if that's not possible
• please draw me some considerations, and feel free to give me some feedback
