[contrib.glfw3] New version (emscripten-core#22103)

Contains 2 emscripten-glfw version with following release notes:

#### 3.4.0.20240617 - 2024-06-17 | emscripten TBD

- Fixed [#3](pongasoft/emscripten-glfw#3): glfwGetKey must return one of `GLFW_PRESS` or `GLFW_RELEASE`

#### 3.4.0.20240616 - 2024-06-16 | emscripten TBD

- Implemented `glfwGetClipboardString`. Note that due to the async (and restrictive) nature of the 
  `navigator.clipboard.readText` call, this synchronous API returns whatever was set via a previous call
  to `glfwSetClipboardString` and ignores the external clipboard entirely.
