no such file or directory errors fix

[Manik2708]

Fixes: #8

1. Now if go.mod and other languages entry file are not added to version control, error will be thrown
2. Warning is also appended with the custom message.

This PR also focuses on one of the problem which I faced during contribution. I was not able to use debugger to test my changes. Rebuilding again and again can be tedious, so I tried to write test for git.go. This test is not a Unit Test as those includes mocking. Mocking git is complex and may include DI, so I approached it by another way. This test create a bsf-temp directory outside the project folder and delete it after the test is completed. I have to create it outside the project directory because the git tree of project should not be hampered. Now testing the git pkg is very simple. But this has some problems:

1. bsf-temp could contain personal data of developer and tests include deleting this folder, so it may lead developer loosing data. But this can be fixed by creating random name folders for testing or asking the name of temp folder from developer during setup.
2. Tests can be slow, on my machine 11 tests are taking 0.002 seconds.

If my approach is right, then I can work on testing build and init command as these commands are very much prone to changes.

And if there is some problem I can remove git_test.go from this PR

• Commit the files and push.

I am little confused regarding the build in CI. It is using the build command of bsf itself to build the project, but the recent changes will throw the error if go.mod are not added to git before building!

I finally got to know why this error was coming, go-git return file as UNTRACKED if it is committed. I have raised an issue in go-git but for now we will assume that if status map doesn't have a file then it is committed! As we are checking the language through langdetect, if it returns other than unknown, it will mean files are present, and if those files are absent in status map, means they are committed! Although I think go-git should track committed files also!

Finally CI passed:)
