purgeAdmin should also send request.body to cacheStore.clearByUid

[fliptaboada]

Hey team!

I believe the purgeAdmin function should also include ctx.request.body on the params that's sent to cacheStore.clearByUid allowing for url paths that include more than just the id.

Reasoning for that is that today when you hit save on the admin, the params object only include the id of the object, only purging urls that include :id as a result and not working for :slug or other cases, so this example here: https://strapi-community.github.io/strapi-plugin-rest-cache/guide/strategy/cache-custom-routes.html#frontmatter-title does't seem to be purged when hitting save, only when you explicitly click Purge REST Cache on the entity (that already adds the whole object to the cacheStore.clearByUid call).

Here's the change I did that seem to fix the issue:

diff --git a/node_modules/strapi-plugin-rest-cache/server/middlewares/purgeAdmin.js b/node_modules/strapi-plugin-rest-cache/server/middlewares/purgeAdmin.js

Let me know if that looks good to you guys and I can also send a PR with this.
