As a shop owner, I can see the plan name on the "A payment collection failed" email

Is your feature request related to a problem? Please describe.

As a shop owner, I can't see which plan a payment has failed for, and if my subscriber has multiple plans it's ambiguous / confusing if one payment succeeded but another failed.

Real customer experience*: "Just got this although when checking he's paid 7th October"
Cause: Their subscriber has paid successful on the same day for one plan, but payment failed for a different plan on the same day.

Describe the solution you'd like
As a minimum, include the plan name on the "A payment collection failed" email.

Describe alternatives you've considered

On the "A payment collection failed" email provide full details of every plan. << This is too much as this stage. Perhaps better simply link in the email to the subscribers overview page (in another issue)

Additional context

*"Yea its not clear on the failed payments we struggling with the system chasing up constantly with failed payments doesn't the system email them as well as us, also has shared we could do with more info on the failed payment team ect"

support> Sorry what do you mean more info regarding the team?
shop owner>When the email is sent to us what team
support>We'll include the team name in the email for you
shop owner>👍

testing

We'll need to re-create the payment failed scenario (during a subscription payment update/charge) to verify this
