Fix CLI encoding of JSON objects

[stnguyen90]

When setting a JSON object string at the CLI, it is considered a string
and passed to the API as a string, even though it's expected as an
object. This change ensures that JSON object strings are decoded into
PHP arrays so that they are properly encoded when sent to the Appwrite
API.

Closes: appwrite/sdk-for-cli#14

Hmm I believe the CI build is failing due to the recent CA certificate expiring, and not due to my code. Should I look into fixing that as part of this PR?

I fixed the problem by updating the image to run the php sdk test for php version 7 to php:7.4-cli-alpine.
