Notebooks: Unable to load github notebook extension on linux

[deepak1556]

Testing #93742

1. Tried both 0.0.4 and 0.0.3 version from the release page
2. Follow error message is shown on console when the extension is loaded

This is because the vsix @jrieken uploaded ships with OctokitProvider.js while on Linux, file paths are case sensitive. I updated the vsix on the release page but still leave this open, then @jrieken remembers to update the file name locally ;)

I blame it on the extract-to-file refactoring from TypeScript. It makes uppper-case filenames and when renaming them to lower-case the compiler doesn't re-emit/clear

This casing-fix is now in 0.0.5 - https://github.com/microsoft/vscode-github-issue-notebooks/releases
