What problem was encountered?

It is a common scenario to use a static version for azcopy. Production upgrade usually needs careful validation.

The doc https://learn.microsoft.com/en-us/azure/storage/common/storage-use-azcopy-v10#obtain-a-static-download-link shares how to get the static download link of the current aka.ms/downloadazcopy-v10-**. However, it is now easy for a previous version.

In #680, someone introduced a way to get the link by pattern https://azcopyvnext.azureedge.net/releaseyyyymmdd/azcopy_linux_amd64_XX.YY.Z.tar.gz. But the trickiest part is the release date has some skew so there might be some guess.

So, it will be great if the official doc can provide a user-friendly permanent links.

Some possible approaches

1. Allow anonymous listing for https://azcopyvnext.azureedge.net/, so that users can browse to get the desired version.
2. Always provide static links on Github release page. Actually, a few releases provided such links while most were not.
3. Summarize a list of historical versions on github repo or MS docs.
4. Use a 100% predictable link pattern for https://azcopyvnext.azureedge.net/***

How can we reproduce the problem in the simplest way?
