Since upgrading mautrix-slack (and pinning to v0.1.0) in e4b54c37fe258b17f49dd7ed58a18ef3abac1c41,
we expect double-puppeting to require the new appservice double-puppeting method.

This commit switches the mautrix-slack bridge to it.

Since upgrading mautrix-signal (v0.6.3 -> v0.7.0) in 76fec0b8632804194ae54dce3328fef2b6e6b3c2,
we expect double-puppeting to require the new appservice double-puppeting method.

This commit switches the mautrix-signal bridge to it.

Bridges will be switched to this new method in future patches.
