This PR promotes the CSS, JS and FONTS files used by API reference to
the `static/css`, `static/js` and `static/fonts` directories
respectively. The intent is that for future releases, when generating
API reference docs, only the `index.html` and `navData.js` files need to
be copied from the generator tools.
Details of changes:
- `jquery-3.2.1.min.js` file is replaced by `jquery-3.3.1.min.js` to
align with the version used by Docsy. We can investigate in the future
whether this can be shared. Converging to the same version at least
can reduce the risks of compatibility.
- `jquery.scrollTo.min.js` moved to `static/js` file and renamed to
`jquery.scrollTo-2.1.2.min.js` so we know the version from file name.
- `scroll.js` moved to `static/js` and renamed to `scroll-apiref.js` to
siginify that it is used by API reference.
- A `README.md` file is added to `static/js` directory for describing
the purposes of the these files.
- `bootstrap.min.css` moved to `static/css` and renamed to
`bootstrap-4.3.1.min.css` so that it can be shared and its version can
be easily discovered.
- `font-awesome.min.css` moved to `static/css` and renamed to
`fontawesome-4.7.0.min.css` for the same reason.
- `stylesheet.css` moved to `static/css` and renamed to
`style_apiref.css` to siginify its purpose.
- A `README.md` file is added to `static/css` directory for describing
the purposes of the these files.
- FontAwesome fonts files moved to `static/fonts` so that they can be
shared across API reference versions.
- Current API reference (1.18) is modified to reference the relocated
files. Upstream generator change on the way
(kubernetes-sigs/reference-tools/#161).
