Update the documentation and include the exclude argument

[hideintheclouds]

This guide does not include all the available arguments:
https://github.com/eNeRGy164/LivingDocumentation/blob/main/docs/guide.md

Meanwhile there seems to have been a PR to exclude certain projects from the analysis.
The option to exclude is displayed in the Options class:
https://github.com/eNeRGy164/LivingDocumentation/blob/main/src/LivingDocumentation.Analyzer/Options.cs

The documentation should be updated to specify that

[eNeRGy164]

You are right, this should be updated.
