Hugo upgrade to 0.121. Docsy update

[josunect]

• Hugo upgrade to the last version: 0.121.1: https://github.com/gohugoio/hugo/releases
• Docsy upgraded to 0.8.0: https://github.com/google/docsy/releases
• Added new type parameter to blocks/section (For the index page)
• Added new step npm build in the theme docsy to avoid missing dependencies for postcss or fontawesome
• Included twitter as excluded urls as a workaround (Now the profile requires authentication)

Great update @josunect, it was really needed. One question, have you updated devDependencies autoprefixer and postcss-cli? With +5000 file changes I am not able to check it (browser hangs)

[josunect]

@ferhoyos no, it was not updated.

Ok, as we are updating kiali.io stuff, I think it would be a good moment to update them too (postcss has security vulnerability). Since the PR has been already reviewed by @hhovsepy, it can be done afterwards.

According to docsy documentation:

Starting in version 8 of postcss-cli, you must also separately install postcss

npm install -D postcss

I've updated the version for the dev dependencies.
