feat(firestore-stripe-payments): allow to be specify trial period days

[jauntybrain]

Allows to specify number of trial period days before initiating checkout flow.
Does not depend on the now-legacy trial_from_plan parameter.

Fixes #599, #274

@jauntybrain Thank you!

I was waiting for this fix

@pr-Mais Do you know if https://extensions.dev/extensions/invertase/firestore-stripe-payments deployed with such fix ?

EDIT: Resolved by updating to the intertase firebase extension.

To anyone experiencing something similar, make sure you uninstall stripe/[email protected]
and install /invertase/[email protected] from the firebase extensions hub.

Potentially a noob problem, but when I specify trial_period_days its not taking me to a trial page. It is taking me to a regular subscription page without the subscription days added. Don't understand what i'm doing wrong.

Invertase stripe firebase extension. Firebase v9.

SNIPPET:

document.getElementById('start-free-trial').addEventListener('click', async () => {
            try {
                const checkoutSessionRef = collection(db, 'customers', user.uid, 'checkout_sessions');
                const docRef = await addDoc(checkoutSessionRef, {
                    price: 'price_fake1OdlyKKhmfO9fl4z8ZX65Qma',
                    trial_period_days: 7,
                    success_url: window.location.origin,
                    cancel_url: window.location.origin
                });
