Document incorrect storage adapter mentioned in installation example (SQLite → Redis)

[Sho2010]

First of all, thank you for maintaining this awesome project!

Description

I noticed a small inconsistency in the documentation. The installation section mentions SQLite as the storage adapter, but the example command actually installs @keyv/redis. Additionally, the rest of the documentation refers to Redis, not SQLite.

keyv/packages/website/site/docs/caching/caching-nestjs.md

Lines 19 to 24 in a09f473

	## 2. Installing Keyv and its Dependencies
	To begin, install Keyv and a storage adapter of your choice. In this example, we'll use SQLite:
	```bash
	$ npm install cacheable @keyv/redis --save
	```

@Sho2010 - thanks for the catch! Updated the code and should have it pushed live in a week or two.
