Feature: Add Open in Gateway

[FledgeXu]

Is your feature request related to a problem? Please describe.
In #1813, the user wants a feature which is showing the downloading progress in the WebUI. However, If users can download through the browser, they can get the download progress they want. So if we can add a new Button called Open in Gateway orOpen in Browser, it will be convenient.

Describe the solution you'd like
Before:

After:

Describe alternatives you've considered
Or Add a Button to help users copy the gateway URL of a file.

Additional context
We can use ipfs config Addresses.Gateway to get Gateway address.

Notes from triage:

• let's not add another action, it will be confusing (proposed one is a duplicate of Share)
• right now the Download button uses JS API and a blob: as a source
• fix here is to switch to HTTP link at a local gateway
  • single file would have /ipfs/{cid}?filename=foo&download=true to ensure proper `content-disposition
  • a directory – tbd, either /api/v0/ or ?format=tar (whichever is available when this is tackled)
    • ideally, we would implement this when /ipfs/<cid>?filename=foo&format=tar is provided (Gateway support for /ipfs/{cid}?format=car|raw|... kubo#8234), but faking it with something like ``/api/v0/get/?arg=&archive=true&compress=true&filename=foo.tar.gz` could also work

I agree with changing the Download button instead of adding a new action.
About directory downloading,?format=tar needs ipfs/kubo#8234. However, Windows doesn't support tar unarchive. Maybe using zip is a better choice?

@FledgeXu You mean GUI? Support for tar has been included in Microsoft Windows since Windows 10:

Adding ZIP would require changes to go-ipfs – blocked by ipfs/kubo#6104

[FledgeXu]

@lidel Yes, I just tested it. Windows still doesn't support the *.tar in GUI.

I believe this should be fixed with #1894. Please let us know if you continue to have issues.
