[Bug]: Increase timeout or add retry for downloading vega binaries in the visor after the protocol upgrade

[daniel1302]

Problem encountered

We got an issue after the last protocol upgrade, where vega was unable to download vega binary and We got the following error:

Dec 28 10:02:13 be1.vega.community visor[1444236]: Error: failed to prepare next upgrade folder: failed to auto install folder "/home/vega/vegavisor_home/v0.73.10" for release "v0.73.10": failed to download release assets for tag "v0.73.10": failed to download asset "vega-linux-amd64.zip" of type "v0.73.10" for tag "application/zip": failed to read  "/home/vega/vegavisor_home/v0.73.10/vega-linux-amd64.zip": context deadline exceeded (Client.Timeout or context cancellation while reading body)

We should increase the timeout or add retry

Observed behaviour

As above.

Expected behaviour

Vegavisor can retry download and unzip vega binaries.

Steps to reproduce

1. Start the network
2. Make your network slow (add rate limit on the router)
3. Propose the protocol upgrade.
