Update "send"

[jhil]

Before submitting a new icon request, please confirm the following:

• [X] I have searched all issues to make sure there isn't a request for this icon.
• [X] I have searched the current library to make sure the icon doesn't already exist.
• [X] I understand that brand icons are no longer being added and I can use SimpleIcons for my brand icon needs.
• [X] I only intend to request a single icon (or a few near-identical ones) in this issue.

What would you use this icon for?

Google updated their send icon (and associated variants) to a more modern design. Can we update all of ours? Not sure the protocol for updating/adding direct Google SVGs. If needed, we can keep the old ones as -variants, but they're probably too similar to be distinguishable by most people.

Give us an example of what this icon might look like.
