Be consistent in recommending Playwright or Puppeteer

[honzajavorek]

As of now, the Academy:

• Has a course on Puppeteer and Playwright, where it explains how I should like Playwright more.
• The course is Puppeteer and Playwright though, not Playwright and Puppeteer. Devil is in the details! 😈
• Many other examples throughout the Academy mention Puppeteer exclusively, with zero mentions of Playwright.

It seems to me like if the Academy had everything in Puppeteer, but then someone decided Playwright is better and should be retro-actively added. So it was added to the course (with bugs, see #961), but nowhere else.

I think we should choose whether we want to express opinion on which is better, or not.

• If we want to express opinion that Playwright is better, we should provide explanation why we think that (done!), put it first everywhere (not done), and all examples should be in Playwright by default (not done). If we want to include Puppeteer, e.g. in the course, that's okay.
• If we're not sure which is better, we can just provide tabbed examples for both, but consistently everywhere. We should remove the explanation why Playwright is recommended, and we should treat them as equals.

Agree with making Playwright the default everywhere. It is marginally better, just like next version of Puppeteer, doesn't really matter that much.
