Issue auto-guessing project file

[MrSFGriffin]

Hello,

I hit an issue where find all reference was not working. I identified the issue as being due to getProjectFileAutoGuess only search upto 2 directory levels, which meant it was not reaching the .nimble file directory, and so had to use a less certain method than nimble dump to identify the project file. This led to the wrong project file being guessed, which broke the referencing functionality. I wrote about it all at: https://forum.nim-lang.org/t/12538#77190.

It can be fixed simply by uping the number of directory levels the autoguessing travels in search of the .nimble file. In my local langserver repo I upped it from 2 to 10 to get things working.

Do you want me to create a pull request with my change?

Sure, go ahead. Although a better solution would be to make nimble dump work in subfolders.
In any case, make sure to add a test case showcasing your issue in tprojectsetup.nim
