chore: add factorypath to gitignore

[MartinWitt]

This was missing inside the .gitignore. The gitignore seems kinda small, have you thought about simply adding something like this https://www.toptal.com/developers/gitignore/api/java,visualstudiocode,eclipse,intellij,maven,gradle ?

Hi @MartinWitt !

Thanks for your PR. I assume .factorypath is for development on Eclipse?

I always add globs to .gitignore when I know I want to ignore them. For example, templates also ignore the jar files but in #696 we need the sonar-java.jar to execute as a sonar-lint plugin. Of course, this is one exceptional case, but I feel the generic .gitignores are more verbose than they need to be.

From my understanding, the eclipse compiler generates these because vscode has no more resource files inside the project folder. In short it appears during my development.
