i.eodag: remove experimental tool warning

[veroandreo]

I suggest removing the warning since the GSoC was completed successfully some months ago, EODAG released 3+ version that solved several issues we dealt with during the development of the tool and, last but not least, the warning clutters every text output in the terminal

@HamedElgizery what do you say?

Yes, I agree. EODAG 3 has solved most, if not all, of the issues that we faced.
I also think IMHO, that it would be helpful if we restrict the module to only use EODAG 3+, and throw a fatal error if the version is below 3.

if int(eodag.__version__.split(".")[0]) < 3:
    gs.fatal(
        _(
            "eodag 3.0.0 or higher is required. eodag {} was found.".format(
                eodag.__version__
            )
        )
    )

Maybe we can add this after the try except block to force the usage of EODAG 3:

if int(eodag.__version__.split(".")[0]) < 3:
    gs.fatal(
        _(
            "eodag 3.0.0 or higher is required. eodag {} was found.".format(
                eodag.__version__
            )
        )
    )

Not sure if there is a different format for these type of error messages?
