remove: unused dependency puppeteer

[fredericrous]

I am getting the following error when I run yarn build on mac m1

❯ npx yarn build                                                                                                                                                        20:13:54

Directory: /Users/frederic.rousseau/Developer/Perso/gridstack.js/node_modules/puppeteer
Output:
The chromium binary is not available for arm64: 
If you are on Ubuntu, you can install with: 

 apt-get install chromium-browser

/Users/frederic.rousseau/Developer/Perso/gridstack.js/node_modules/puppeteer/lib/cjs/puppeteer/node/BrowserFetcher.js:112

I can fix it with:

brew install chromium
export PUPPETEER_SKIP_CHROMIUM_DOWNLOAD=true                                                                                                                          
export PUPPETEER_EXECUTABLE_PATH=`which chromium`

However, puppeteer is not used and seems to have been introduced by mistake with commit 181dbcc8

actually puppeteer was there before 181dbcc, but you're right doesn't look like it's used. thanks.
