Yes, but Jet2holidays have already pushed their 'all holidays cancelled until' date back several times so there's no guarantee that they won't do so again.
They've been great during this pandemic though, but they could word their statements better as they're saying 'we will start again on X date' when what they really mean is 'all holidays starting before X are cancelled, situation still under review for later dates'.
Jet2holidays are currently doing fee free changes until 15 July, but if it's not looking like travel is opening up within the next couple of weeks, it's very likely to get put back again, when it will include the OPs holiday. Could you push your holiday back until later in the year, or even next year, OP?
If not, you just need to wait and if the holiday isn't cancelled (I think it's quite likely that it will be, but there could be a turn around, but lots of things need to change, like the FCO advisory, quarantine restrictions both in and out) for holidays to be viable) you need to think about going, and sorting yourself with a passport.
But if you really can't face going, it's probably worth asking Jet2 if you can change the date, they might be accommodating in the circumstances.
Moneysavingexpert also has helpful advice, but one thing, why on earth did you pay by Paypal? You have a lot more protection from your card provider if you use it directly (credit card is best)
