fix: Improve Jupyter performance

[DanielSchiavini]

What I did

Improved the jupyter plugin performance considerably
Fixed the empty elements while calling javascript

How I did it

• Minified JS with command npx uglify-js --mangle -o jupyter.min.js -- jupyter.js
• Instead of injecting the whole ethersJS library, just inline the wallet calls
• Only inject the JS triggers once for JupyterLab - in colab this does not work

How to verify it

• Jupyter plugin should keep on working but much better

Description for the changelog

• Improved and simplified JupyterLab and Colab plugin

i'm not convinced we want the complexity of introducing minification into the build process. fwiw after compression the minified version saves 900 bytes:

(boa) ~/titanoboa $ gzip -v < boa/integrations/jupyter/jupyter.js | wc
 61.7%
      6      47    1822
(boa) ~/titanoboa $ gzip -v < boa/integrations/jupyter/jupyter.min.js | wc
 47.0%
      3      19     949

code review note: discussed refactoring the jupyter.js file into a full-on extension, but it seems to introduce more complexity than it is worth.

just tested this -- works amazing! and it's deployed to try.vyperlang.org now :)
