Futures Curve: minor cosmetic improvements

[skhan877]

Catering for #4886

1. Raw table column name changed from "Futures" to "Last Price" - in both interactive and basic view.
2. Contract names "prettified" more in-line with convention (mmm-yyyy). Also amends excel output format.

3. Curve graph x-axis lines up actual contract months now, rather than continuous dates.

Hi @skhan59bbk, thanks for the PR and the improvement! The code linting is failing because it has not been formatted according to Black's wishes. Run it from the command line at the root of the OpenBBTerminal folder:

black openbb_terminal/futures

However, because the expected outputs have been changed, you will also have to re-record the unit test cassettes so that the changes to the results are captured.

pytest tests/openbb_terminal/futures --rewrite-expected 

This will update a few files in the /tests folder. Add those, along with the changes made by the code linting to the yfinance_model and yfinance_view files, in a commit.

Ah my bad. Linting fixed but pytest is asking me to uninstall brotli - is this expected?

Yes. We have historically run into some issues with the encoding used there. pip uninstall brotli -y then you can rewrite the tests
