Social media icons: review colours

[inesdgomes]

As discussed, consider to use ILO blue (instead of grey) on social media icons in a white background.

Thanks @beatrizmartinmartins Moving it to development.

@justintemps Very small change: social media icons showing on a white background should be in ILO blue rather than grey. This should be changed in the social media component and in the hero card.
