JWKS endpoint is not responding with a valid alg

Hi,

The JWKS endpoint respond with an invalid alg for the key cloudtasks-emulator-test.

Example:

{"keys":[{"alg":"RSA256","e":"AQAB","kid":"cloudtasks-emulator-test","kty":"RSA","n":"vhHj4zZSEg7q1-BdSbzSivtmn4EWF_PZIF7gAH-4iqm7v22MN-2wvnmpNLQG_-LeJ5M39kDHWt2ei3HEsxPxbEeeHRzCm23AgXDGTkjuUUXi7GP1nQmWcZnyckD0jr8kZO789pauck61GvnQhtdl4mP3JCCXPI0dJvbkr76ni-hMnjpB7GyChEglIArshTNPwhHm-6M0c4R3uVvzQUpuE7CEcisNH1u8HM0aOnQKXYc42a3P4yllpD70jNt008StXyyIIwN4LFT9-5vM9FrBEpY4k9EAggU2R7FEodnky6e8grPV2b0z2eRLu4jgITPMzyyqYc6LccEPsn99XqkF1w","use":"sig"}]}

The alg is RSA256 instead of the expected RS256. This makes it very hard to use with library like the java google-auth-library (which is used by the official cloud tasks) as it expects the correct RS256 instead.

Best,
