Subject: Add additional ERB DummyCompiler tests

This adds a few additional tests to the commits by eileencodes (https://github.com/rails/rails/pull/35497) and rafaelfranca (https://github.com/rails/rails/commit/cfa22f1a4b5e8b95ee01a432168de2f831b3f788). The additional tests cover several more ERB tag formatting cases such as multiline tags, conditional statements that result in duplicate keys, and multiple erb statements on a single line.
