chore: more faq when migrate to buf

</code></pre><p>Run <code>make gen</code> to get fun of course.<h2>FAQ</h2><p>If use <code>vendor</code>:<ul><li>Replace <code>buf generate</code> with <code>buf generate --exclude-path vendor</code>.<li>Replace <code>buf format -w</code> with <code>buf format -w --exclude-path vendor</code>.</ul><p>Replace <code>import "third_party/googleapis/google/api/annotations.proto";</code> with <code>import "google/api/annotations.proto";</code><p>Delete <code>security_definitions</code>, <code>security</code>, in <code>option (grpc.gateway.protoc_gen_swagger.options.openapiv2_swagger)</code>.<p>The last step is delete <code>prototool.yaml</code>.<h2>Thanks</h2><ul><li><a href=https://github.com/uber/prototool>uber/prototool</a><li><a href=https://github.com/bufbuild/buf>bufbuild/buf</a></ul><a href=mailto:hauvipapro+posts@gmail.com>Feel free to ask me via email</a>
