remove trusted-resources-config

This commit removes trusted-resources-config. The deprecation is
announced in release v0.45. The reason of removing is that
trusted-resources-config is used to store public keys for verificaiton
but Verification Policy has already covered all the functionalities and
has more advanced features. Since there are not any other fields in
trusted-resources-config we decided to remove it.

Closes tektoncd#5852

-Multiple keys reference should be separated by comma. If the resource can pass any key in the list, it will pass the verification.

-We currently hardcode SHA256 as hashfunc for loading public keys as verifiers.

-Public key files should be added into secret and mounted into controller volumes. To add keys into secret you may execute:
-
-```shell
-kubectl create secret generic verification-secrets \
