Migrate uses of struct.to_proto (#6801)

c-mita · web-flow · commit 8f3deeb9a0b4 · 2024-03-26T10:07:02.000-04:00
Reapplies #6778 after #6721 inadvertently reverted part of it. The "to_proto" method on Starlark structs is deprecated and shouldn't be used. Instead, the proto module's "encode_text" function should be used. (https://bazel.build/rules/lib/toplevel/proto) It, along with "to_json", can be disabled in Bazel using the flag --incompatible_struct_has_no_methods The underlying implementation is the same, so there should be no observable changes in final outputs.
