ci: add ignore-scripts to Node package manager config (20260527-193412)

This PR was generated by sec-cli github repositories ignore-scripts update.

What changed

Package managers detected: yarn

Updated config files (directive appended):

• .yarnrc.yml

Why

Running npm install (or yarn, pnpm, bun, npx) without restricting
postinstall scripts allows dependency lifecycle hooks to execute arbitrary code
during installation. Setting ignore-scripts=true (or the equivalent for your
package manager) mitigates this risk.
