[eslint-plugin] set package version back to 3.0.0 (#30090)

to fix broken nightly pipelines where we update `@azure` package
versions to
nightly versions and dependency versions to a range for their nightly
versions.
Versino `^3.0.0` would not get updated because of the following chech in
`set-dev.js` then `rush install` would fail to find matching one and
report error.
