Add support for new binaries (polkadot)

[pepoviola]

We should add support in our setup command for the upcoming new binaries in polkadot.
Reference issue: paritytech/polkadot#7337 (comment)

We should download in the same directory and also set them as executable.

@pepoviola we have this issue: #434 is it relevant?

[mrcnski]

I've just merged paritytech/polkadot#7337, so I can knock this out if no one's started on it yet?

[wirednkod]

@mrcnski Im on it - sorry did not assign it to me

[mrcnski]

Awesome, for easy reference here the two new binaries are polkadot-prepare-worker and polkadot-execute-worker.

[wirednkod]

@mrcnski Just to make sure we are on the same page - there will be no more polkadot binary? and it will split in these 2? Also can you please let me know if these binaries have official releases (and example links of those)?

There is still the polkadot binary, those are two new ones in addition.

Also can you please let me know if these binaries have official releases (and example links of those)?

I just merged the PR today so no official releases yet AFAIK. Let me know if any other questions. :)

Thank you @mrcnski . I will push a draft PR and add you as a reviewer - and wait for some release to test it - if you are ok with that

@wirednkod just a heads-up since a new release will be soon available.
