de93fc91 - Add more code splitters (go, rst, js, java, cpp, scala, ruby, php, swift, rust) (#5171)

Add more code splitters (go, rst, js, java, cpp, scala, ruby, php, swift, rust) (#5171) As the title says, I added more code splitters. The implementation is trivial, so i don't add separate tests for each splitter. Let me know if any concerns. Fixes # (issue) https://github.com/hwchase17/langchain/issues/5170 ## Who can review? Community members can review the PR once tests pass.
