[feature] customize the release details

[its-dibo]

is there an option to customize the release title and details like this:

["@semantic-release/github",{
  release:{
    details: `<details><summary>changes</summary> ${changelog} </details>`
 }
}

also, we need the variable ${changelog}

Yeah, customizing Release title would be great. Voting +1
