fix: declare dependency "buf.build/googleapis/googleapis"

[Kynea0b]

Description

When you run buf generate ./proto in the root directory, you will receive the following warning: In fact, the dependency description is lacking.

WARN    bufimagebuild   File "cosmwasm/wasm/v1/query.proto" imports "google/api/annotations.proto", which is not found in your local files or direct dependencies, but is found in the transitive dependency "buf.build/googleapis/googleapis". Declare dependency "buf.build/googleapis/googleapis" in the deps key in buf.yaml.

This is a PR to correct this warning.
Declaring the dependency resolves the warning.

Is it necessary to specify a version or commit bash as in cosmwasm/wasmd?

@170210
Thank you for confirming.
I think it will be necessary.
Currently, I think it is better to leave it unspecified for the following reasons.

• Other dependent specifications such as buf.build/cosmos/gogo-proto and buf.build/cosmos/cosmos-proto are also not specified.
• We are currently considering the version of cosmos-sdk.

Version specification has been made into a separate issue.
