Add back support for node 8

[jaredpalmer]

Thank you @wessberg for the help

@wessberg need you bump version of browserlist generator in rollup-plugin-ts and then publish .69

[wessberg]

I've already bumped the dependency and published a new version, so we should be good 😊

Ah, didn't change the engine property from >=9.00 to >= 8 inside of browserslist-generator before publish. I'll get a new version published later today and will update here when it's done.

Fixed in v1.1.69!

I see that you're having the issue with another one of my packages on the CI pipeline. Let me fix that one too.
