Fix Tuya temp sensors _TZE200_vvmbj46n, _TZE284_vvmbj46n

[TheJulianJES]

Proposed change

This PR fixes an issue where various config options would not show up for the following Tuya temperature sensors:

• _TZE200_vvmbj46n (since HA 2025.2.0, Add Tuya sensor _TZE200_vvmbj46n #3776)
• _TZE284_vvmbj46n (since quirks dev, Add Tuya temp sensor _TZE284_vvmbj46n variant #4006)

This also removes unnecessary "fixing" of negative temperature values for these devices.
Both Tuya spells are also enabled due to Z2M source mentioning this being required (might not be true, but doesn't hurt to enable this).
Affected devices that are not reporting need to be re-paired on a version with this bugfix.

Additional information

Follow-up PR to:

• Add Tuya sensor _TZE200_vvmbj46n #3776
• Add Tuya temp sensor _TZE284_vvmbj46n variant #4006

PR is untested, but looking good when comparing to Z2M code.
