chore: change grants program enticement

[wyhaines]

Since the grants program has launched, the "coming soon" wording should be updated.

Description

Now that the grants program has launched, this enticement should reflect that.

Additions and Changes

The new enticement just reflects that the grants program is an active thing, and that applications are actively being accepted.
