Fix ember data request service link

[pomm0]

This link is pointing to the ember octane page which is probably not intended. Wasn't sure which url should be used and figured that https://api.emberjs.com/ember-data/release/modules/@ember-data%2Frequest is probably the best page to link. I'm happy to use a different url if there is a better place to link to, please let me know.

Possible other links I've considered:

• https://api.emberjs.com/ember-data/release/modules/@ember-data%2Fstore
• https://github.com/emberjs/data/tree/main/packages/store
