feat: update icons to v1.4

[Joeao]

This change adds all icons that were introduced in https://github.com/phosphor-icons/phosphor-home/releases/tag/v1.4.0.

My process was as follows:

• Emptied existing svgs directory
• Copied contents of release v1.4 SVGsdirectory into this repo's svg directory
• Ran npm run generate
• Ran npm run prepare for local testing
• Copied new lib into node_modules for local testing

If there's nothing more to the process, then it's ready for usage. Otherwise please give feedback and I'll make changes where necessary.

Hey @Joeao did you try to use the new icons in the example app to make sure every icon is working properly?

[Joeao]

I didn't use all the icons, just one actually. I'll implement more of the new icons into the app as part of the self-review, will report my findings.

[Joeao]

I'm happy with it
