feat: add support for more complex filters in Portfolio widget

Browse Source 
See https://isotope.metafizzy.co/filtering.html

E.g. filter on multiple tags:

```
  filter_button:
    - name: All
      tag: '*'
    - name: Machine Learning
      tag: ML
    - name: Computer Vision
      tag: CV
    - name: NLP
      tag: NLP
    - name: CV or NLP
      filter: '.js-id-cv, .js-id-nlp'
    - name: ML and NLP
      filter: '.js-id-ml.js-id-nlp'
```
