Auto-Not-So-Matic: Fix two matic.network URLs to polygon.technology (#…

…3483)

Looks like matic.network has been fully decommissioned, and for both gas
prices and for the PoS WETH asset, we were relying on it. Move to
polygon.technology equivalents.

In practice, the asset SVG for PoS WETH won't be used because newer
versions of the Polygon token lists don't include the broken WETH asset
that we were substituting in. We keep it because it's referenced in a
migration and I would rather not try to figure out if it's safe to kill
the migration for now.

## Testing

- [x] Switch to Polygon
- [x] Try to send an asset. You should be able to get to the send
transaction screen with a populated gas price.
- [x] Look up ETH under the swap target while on Polygon and make sure
you see ![](https://assets.polygon.technology/tokenAssets/eth.svg) as
the icon. The changes in this PR shouldn't really affect this, but might
as well check!

Fixes #3482 .
