fix(deps): Update express mw to latest graphql-playground-html

[mmmeff]

graphql-playground-middleware-express package.json should now point to the latest version of html.

My team's licensing automation is still failing because the 1.6.13 fixes aren't being picked up by this pinned version

@HuVik The last CR I cut didn't quite fix this issue sadly - I think there's an issue with the release scripts in the monorepo that forgot to update this dependency version.

Any chance we can get this one fast tracked well? We're still blocked by this on my team :(

Any updates on this? We also suffer from license linting failures because of this.

gonna make a security update PR today! this PR would need a yarn.lock bump as well.

for a full security update, this is going to require a few changes, and it's not proving easy to do without deleting the lockfile and completely regenerating it, which has already introduced its own set of problems. possibly i will need to manually change the lockfile from the master version, remove these last 5 security issues with hapi manually, and make sure it re-generates as such. it also appears this repo also doesn't have tests which has me worried

thanks @mmmeff , lets see if dependabot generates a lockfile update for us. i'm not familiar with having 7 yarn lock files in one monorepo! yikes, haha
