[clang-format] Fix indent of 'key <...>' and 'key {...}' in text protos
Summary:
This patch fixes the indentation of the code pattern `key <...>`and `key {...}` in text protos.
Previously, such line would be alinged depending on the column of the previous
colon, which usually indents too much.
I'm gonna go ahead and commit this since it's a straightforward bugfix.
