Action regularly fails due to timeouts

[lwasyl]

When using this action, we see regular failures due to the download action taking longer than 30s:

the entire job fails after that. Since the Github action is fairly simple, we can switch to fetching the CLI directly. When we do that, the CI timings show that downloading Doppler CLI usually takes about 1s, but occasionally spikes to even one minute (less on the screenshot but it's an example):

It would be useful if this action

• didn't fail when the downloading takes more than 30s, or retried the download a couple of times
• cached the actual CLI tool (instead of the install script) so the downloading isn't necessary on each build

Might be worth it to consider adding optional support for actions/cache?
