feat(release)!: rewrite ChangelogRenderer to a class API and remove deprecated config (#28229)

BREAKING CHANGE

In Nx v19, implementing a custom changelog renderer would involve a lot
of work on the user side. They would need to create an additional
function making every property available in its declaration and then
call the underlying default one and customize the final string (or
reimplement the whole thing).

E.g.

```js
const changelogRenderer = async ({
  projectGraph,
  commits,
  releaseVersion,
  project,
  entryWhenNoChanges,
  changelogRenderOptions,
  repoSlug,
  conventionalCommitsConfig,
  changes,
}) => {
  const defaultChangelog = await defaultChangelogRenderer({
    projectGraph,
    commits,
    releaseVersion,
    project,
    entryWhenNoChanges,
    changelogRenderOptions,
    repoSlug,
    conventionalCommitsConfig,
    changes,
  });

  // ...Do custom stuff and return final string...
};

module.exports = changelogRenderer;
```

In Nx v20, changelog renderer are classes. The DefaultChangelogRenderer
can therefore easily and granularly be extended and customized, and the
config does not need to be redeclared on the user side at all. We will
improve things even further in this area, but this breaking change is an
important stepping stone.

E.g. for manipulating the final string equivalent to the previous
example:

```js
module.exports = class CustomChangelogRenderer extends (
  DefaultChangelogRenderer
) {
  async render() {
    const defaultChangelogEntry = await super.render();
    // ...Do custom stuff and return final string...
  }
};
```

E.g. for customizing just how titles get rendered:

```js
class CustomChangelogRenderer extends DefaultChangelogRenderer {
  renderVersionTitle(): string {
    return 'Custom Version Title';
  }
}
```
