Lint for JSX file extension

[maximemulder]

Add a lint to ensure JSX only appears in *.jsx and *.tsx files, helping to differentiate React files and standard script files. The files were automatically renamed based on the errors generated, Javascript files that do not contain JSX are still named *.js.

Is there any reason you did this? There isn't a single file with the .jsx extension in LORIS right now. This will cause conflicts with every single javascript PR and seems to be purely cosmetic.

@driusan I think the change is more than cosmetic. First, it helps to differentiate React files from non-React Javascript files (especially since I'd like to merge the js and jsx directories in the future, even if we do not apply the "compile all in one directory" change). Second, it seems to be a community standard, I rarely see code outside of LORIS using .js for JSX. And finally, it does help some tools better analyze the Javascript code (I notably made this change because during my tests, Vite did not work out of the box with JSX in .js files).

Too hard breaking and too little benefit for how controversial it is. Closed.
