[Feature]: @o3r/create should generate end-of-line LF config

[malek-benazzouz]

Context

When generating a project using @o3r/create, do we want the generator to automatically add the LF end-of-line config?

Proposal

To handle the LF config, we could:

1. Add the following line in .editorconfig file: end_of_line = lf.
2. Generate a .gitattributes file containing at least this line: * text eol=lf.
