Make sure ESLint that should only work on TSX are set to only trigger…

… on TSX files (#169361)

## Summary

This makes the newly created i18n ESLint rule actually activate on
paths, and narrows the use of the Telemetry ESLint rule to only activate
on .tsx files. This is done because the rule only makes sense in the
context of JSX.

## More words

Noticed that this:

```
        'x-pack/plugins/aiops/**/*.{tsx}',
        'x-pack/plugins/apm/**/*.{tsx}',
        'x-pack/plugins/exploratory_view/**/*.{tsx}',
```

does not work. 

This:

```
        'x-pack/plugins/aiops/**/*.tsx',
        'x-pack/plugins/apm/**/*.tsx',
        'x-pack/plugins/exploratory_view/**/*.tsx',
```

does.
