BREAKING CHANGE: the minimum required version of node is now v14.17 (#244)

BREAKING CHANGE: `@semantic-release/commit-analyzer` is now a native ES Module

BREAKING CHANGE: When setting the `releaseRules` option to a path, the path must include the `.js` extension, and the file must be an ES Module itself, exporting an array as default

Before:

```json
{
  "plugins": [
    ["@semantic-release/commit-analyzer", {
      "preset": "angular",
      "releaseRules": "./config/release-rules"
    }],
    "@semantic-release/release-notes-generator"
  ]
}
```
```js
// File: config/release-rules.js
module.exports = [
  {type: 'docs', scope: 'README', release: 'patch'},
  {type: 'refactor', scope: 'core-*', release: 'minor'},
  {type: 'refactor', release: 'patch'},
];
```

After:

```json
{
  "plugins": [
    ["@semantic-release/commit-analyzer", {
      "preset": "angular",
      "releaseRules": "./config/release-rules.js"
    }],
    "@semantic-release/release-notes-generator"
  ]
}
```
```js
// File: config/release-rules.js
export default [
  {type: 'docs', scope: 'README', release: 'patch'},
  {type: 'refactor', scope: 'core-*', release: 'minor'},
  {type: 'refactor', release: 'patch'},
];
```
