Fix incorrect string format in js build script #26374 I accidentally met this small problem mentioned in https://github.com/opencv/opencv/pull/25084#discussion_r1710838120 when play with wasm build. It seems https://github.com/EDVTAZ didn't fix it yet, so I create this tiny pr. Additionally, I remove a redundant argument in `add_argument` call. `'store_true'` already set the default, see https://docs.python.org/3/library/argparse.html#action. ### Pull Request Readiness Checklist See details at https://github.com/opencv/opencv/wiki/How_to_contribute#making-a-good-pull-request - [x] I agree to contribute to the project under Apache 2 License. - [x] To the best of my knowledge, the proposed patch is not based on a code under GPL or another license that is incompatible with OpenCV - [x] The PR is proposed to the proper branch - [x] There is a reference to the original bug report and related work - [ ] There is accuracy test, performance test and test data in opencv_extra repository, if applicable Patch to opencv_extra has the same branch name. - [ ] The feature is well documented and sample code can be built with the project CMake |

Building OpenCV.js by Emscripten
Download and install Emscripten.
Execute build_js.py script:
emcmake python <opencv_src_dir>/platforms/js/build_js.py <build_dir>
If everything is fine, a few minutes later you will get <build_dir>/bin/opencv.js. You can add this into your web pages.
Find out more build options by -h switch.
For detailed build tutorial, check out <opencv_src_dir>/doc/js_tutorials/js_setup/js_setup/js_setup.markdown.
