[BUG] Members cache does not function as intended
### Describe the bug.

`interactions` currently has a (somewhat internal) cache for various items like users, roles, channels, etc. It also has one for members, too.

This is obviously a nice feature for developers; however, it does not function correctly. It assumes that a member's ID *alone* can be used as the key for a member. However, a member with the same ID from one guild *is not* the same as a member with the same ID from another guild.

(To simplify that: if you're in two guilds, in the API, despite having the same user ID everywhere, the "you" in each guild is different with differing nicknames, roles, etc., right? The cache forgot about that.)

### List the steps.

1. Fetch a member with a set ID from a guild, guild X.
2. Use the cache to get a member with the same ID as the above from another guild, guild Y.

### What you expected.

In this case, nothing should be returned as we never fetched the member from guild Y.

### What you saw.

The member object for guild X.

### What version of the library did you use?

`release`

### Version specification

4.1.0, though this hasn't been fixed in unstable either.

### Code of Conduct

- [X] I agree to follow the contribution requirements.
