fix: unknown target 'check-torch-mlir-python'

[raayandhar]

When looking through development.md, running cmake --build build --target check-torch-mlir-python like instructed gives the error

ninja: error: unknown target 'check-torch-mlir-python', did you mean 'check-torch_mlir-python'? 

One option is of course to change the docs, but the underscore seems inconsistent with the other targets, i.e. cmake --build build --target check-torch-mlir works just fine.
Another note is that in projects/pt1/python/test/CMakeLists.txt, there actually is this target defined with the hyphen:

add_lit_testsuite(check-torch-mlir-python "Running the torch-mlir Python regression tests" ${CMAKE_CURRENT_BINARY_DIR} DEPENDS ${TEST_DEPENDS} ) set_target_properties(check-torch-mlir-python PROPERTIES FOLDER "Tests") 

So it seems that somehow it is being overriden - making the one line change like I do here in the project name parameter seems to resolve this. But I'm not sure if that's the best solution. Looking for a review and some feedback here on the right approach to fix this.
