Feature Request: Add end date filter

[ipokkel]

Is your feature request related to a problem? Please describe.
When a member has a recurring payment level the "Membership Expires" item on the card displays "Never". This cannot be replaced with a custom value, e.g. the level's next payment date of the recurring billing cycle, as there is no filter for this value.

Describe the solution you'd like
The pmpro_membership_card_since_date filter for the start date allows customizing the value displayed for the "Member Since" item on the card, adding a filter for the end date, e.g. pmpro_membership_card_end_date, where the value is displayed for the "Membership Expires" item on the card could be a useful enhancement allowing developers to customize the value displayed here.

Describe alternatives you've considered
Use a custom template with the required functionality built-in.
