- Update the `github.com/buildkite/terminal-to-html/v3` dependency from version v3.10.1 to v3.13.0. - Version v3.12.0 introduced an incompatible change, the return type of `AsHTML` changed from `[]byte` to `string`. That same version also introduced streaming mode https://github.com/buildkite/terminal-to-html/pull/126, which allows us to avoid reading the whole input into memory. - Closes #4313
