Replace 3rd party domains in examples with example.com

[WyriHaximus]

While using a big tech 3rd party domain like google.com is guaranteed to work, there are special domains like example.com set up for this since the dawn of the internet.

[WyriHaximus]

When this PR is approved and merged I'll file PR's for the other repositories that use 3rd party domains for things like this. But until then, the aim is to keep the discussion about this in one location.

Why not use the canonical documentation domains provided by IANA? e.g. www.example.com, www.example.org. That's what they're there for.

[SimonFrings]

@Bilge Good point, but I don't really see a big difference in using www.example.com, www.example.org or reactphp.org. That's why I leave that decision up to @WyriHaximus and will approve whatever he decides :D

[WyriHaximus]

@SimonFrings To be honest I think @Bilge's point is pretty good that those domains are specifically for this purpose. So I'm leaning more to use example.com then to use reactphp.org at this point. Unless @clue has good reasons to go with either of those two.

[SimonFrings]

@WyriHaximus Fine by me 👍

[WyriHaximus]

Updated the PR changing everything to example.com

[SimonFrings]

One last question, should it be www.example.com or just example.com. Just asking because PR title doesn't match your changes (pls don't hate me 😅)

[WyriHaximus]

@SimonFrings It was mainly about updating the domain name, but updated the PR title and commit message 👍 . If you prefer to have it fully in line, I can also update the branch name and file a new PR from that 😜.

[Bilge]

Can you guys quit bikeshedding in my feed already.

[SimonFrings]

Goodbye google 👍

@WyriHaximus Thank you for looking into this and updating to example.com!
