Thales Macedo Garitezi 1824e7efcc fix(rule_engine): count referenced bridges in from clauses as dependencies (rv5.0) 
Fixes https://emqx.atlassian.net/browse/EMQX-9325

Currently, ingress bridges referenced in the `FROM` clause of rules
are not being accounted as dependencies.

When we try to delete an ingress bridge that's referenced in a rule
like `select * from "$bridges/mqtt:ingress"`, that bridge does not
trigger an UI warning about dependent actions.
