"google/cloud-recaptcha-enterprise": "^2.2",

is full of deprecations in php 8.5

Deprecated: chr(): Providing a value not in-between 0 and 255 is deprecated, this is because a byte value must be in the [0, 255] interval. The value used will be constrained using % 256

These are fixed in protobuf in protocolbuffers/protobuf#24668 and protocolbuffers/protobuf#24666 but we are waiting for the next version of the library to be released
