template-click-events-have-key-events throws error on anchor <a> element

**Describe the bug**

The rule should exclude interactive elements. Buttons are indeed excluded, however, anchor tags with click events (without key events) still cause a lint error:

`My link`

> click must be accompanied by either keyup, keydown or keypress event for accessibility

**Context and configuration**
rule: template-click-events-have-key-events
tsconfig.json:
```
{
"extends": "../../tsconfig.base.json",
"compilerOptions": {
"types": ["jasmine"]
},
"include": [],
"files": [],
"references": [
{
"path": "./tsconfig.app.json"
},
{
"path": "./tsconfig.spec.json"
}
]
}
```
tsconfig.base.json:
```
{
"compileOnSave": false,
"compilerOptions": {
"downlevelIteration": true,
"sourceMap": true,
"declaration": false,
"moduleResolution": "node",
"emitDecoratorMetadata": true,
"experimentalDecorators": true,
"importHelpers": true,

},

},
"exclude": ["node_modules", "tmp"]
}

```

**Expected behavior**

The rule should pass for anchor tags with click events, even if they don't have a key event.

**Environment**

- Version 6.0.1
- OS: Mac OS
- Node.js version 12.18.3
- npm version 6.14.6
- Angular version 10.0.5
- tslint version 6.1.2

Start by locating the implementation and tests for the template-click-events-have-key-events rule. Reproduce the reported anchor example, verify that buttons remain excluded, and consider the work complete when anchor elements with click handlers no longer produce this accessibility error.
