Deprecated option used in docs

[jdillard]

code is used in the Existence example, but has since been deprecated.

Would love to fix that but just started learning/using Vale. Unfortunately, I haven't found the ref to the deprecation yet.

In https://studio.vale.sh, the example leads to:

[2.25.2] [4:1]: has invalid keys: 'code'

The example in the docs works without the code key:

extends: existence
message: Consider removing '%s'
level: warning
ignorecase: true
tokens:
    - appears to be
    - arguably

The tokens are recognized, the rule editor shows [2.25.2] Syntax OK; rule successfully compiled.

Is this paragraph in the docs related?
