Remove xlsx export from CLI's interactive tables

[piiq]

This PR removes the option to export tables to excel from the UI of the interactive table.

The xlsx export in CLI's interactive tables relied on a vulnerable version of the xlsx npm package.

The SheetsJS project that is behind xlsx package does not distribute the latest packages via npm making it a bit harder to follow updated.

Since we have xlsx export functionality on the CLI and platform level and there is still an option to export the data from a the interactive table in machine readable format, I decided to remove the vulnerable dependency instead of trying to patch or find a replacement.

Does this actually change the code in tables.html? AFAICT these front-end components are not directly used.

If it's a table, I still have the options to download it as an Excel file (and it works):

@hjoaquim I've added a few commits that update the built html in the charting library and the corresponding build script.

I've also removed the posthog code and incorporated the css that @deeleeramone used in the template html into the index.css file.

Tables look good, and the export functionalities are working perfectly now. Building the openbb-charting wheel and use it also works as expected.

Tested this and it works and performs well! Thanks @piiq !
