Previously we use ANSI color sequences to highlight TVM script. In jupyter notebook environments, such color sequence will be recoginized and translated to corresponding HTML to display things.
This works fine for most notebook environments (including the jupyter notebook and the VS Code plugin). Recently, thanks to @tqchen, we found that Google Colab does not well support ansi color sequence for 24-bit colors (`JupyterLight` and `VSCDark`) that all its displayed colors are unexpectedly black/gray/white. To also bring highlighting in Colab, in this PR, we directly render the highlighted code with HTML when a notebook environment is detected.
