using shell to evaluate env or expressions

1- if the package support shell, we can do something like that

 [
     
        '@semantic-release/git',
        {
          message:
            "build: release $(jq -r '.name' package.json)-${nextRelease.version} [skip ci]",
        },
      ]

2- we can provide ${ package } placeholder, so we can do something like "build: release${ package.name }-..."

3- apart from supporting shell, we need to change the default message:

• remove "${ nextRelease.notes }", because it often violates commitLint rules
• add package.name by default (useful for monorepos)

No source files, tests, or entry points are named. Begin by locating the plugin's message configuration and package.json handling, then treat shell evaluation or placeholders and the two requested default-message changes as the completion criteria.
