Build fails after HashiCorp APT signing key rotation

Expected behavior: Building Teleport works

Current behavior: Building Teleport fails

Bug details:

• Teleport version: v18.11.1
• Recreation steps: Run make -C build.assets build-binaries

124.5 W: GPG error: https://apt.releases.hashicorp.com/ jammy InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY FC9CA96ACA026560
124.5 E: The repository 'https://apt.releases.hashicorp.com/ jammy InRelease' is not signed.

The issue has been observed from other users obviously: https://github.com/gravitational/teleport/commit/73521d30242b1dda20690cfde53cfd17e59fc4d9

Would be nice if the fix can be merged back so it is contained in future releases
