docs: Add deviceshare plugin dependency warning to Predicate plugin documentation

[csh0101]

Description

Add important dependency information to the Predicate plugin documentation to inform users that the deviceshare plugin requires the Predicate plugin to be enabled.

Changes Made

• Added warning section to both English and Chinese versions of the plugins documentation
• Clearly stated that deviceshare plugin has a dependency on Predicate plugin
• Explained that this implicit dependency can make the plugin ecosystem fragile

Files Modified

• content/en/docs/plugins.md
• content/zh/docs/plugins.md

Rationale

Users may enable the deviceshare plugin without realizing it depends on the Predicate plugin, leading to configuration issues. This documentation update helps prevent such problems by making the dependency explicit.

Before/After

Before: No mention of deviceshare dependency on Predicate plugin

After: Clear warning in both language versions:

• English: "The deviceshare plugin has a dependency on the Predicate plugin and cannot function without it being enabled."
• Chinese: "deviceshare插件依赖于Predicate插件，不能在Predicate插件未启用的情况下独立运行。"
