Why change the string quotes convention?

This project does not have an .eslintrc file so you shouldn't be applying your personal preferences to it. It's better to maintain the existing conventions.

Why change the date format? Used to be separated by /, and now separated by -.

dayjs handles date with this specific format by default, plus it's less confusing
I didnt know in the first place if it was DD/MM/YYYY or MM/DD/YYYY

It's trivial to compare dates in JavaScript, so you don't need a dependency for that.

It's easier to manipulate dates with dayjs, which is the lightest date library I've found

While that's true, the manipulation that you perform is rather trivial even without a library.
In lib/index.js:239 you're just comparing two dates. I'll comment there directly.

The project doesn't currently have a yarn.lock, so please don't commit one.

That's a useful feature that we're currently doing in application code instead of via the dependency. |

What I see you're doing is checking if now <= expirationDate. You don't need a library for that.
I believe you can compare two plain JavaScript date objects with the <= operator directly.
If that's hard to grasp, you can also convert them to a UNIX timestamp (a number) and compare those.
https://stackoverflow.com/questions/492994/compare-two-dates-with-javascript
You can get a date object of the current time via the date constructor without parameters new Date(). Alternatively, you can get the UNIX timestamp by calling Date.now().
So, it would be something like:
return (new Date()) <= new Date(expirationDate)
or
return Date.now() <= (new Date(expirationDate)).getTime()
If there is no expirationDate specified in the license then it returns true, otherwise it checks if today is before or same day as expirationDate
