feat: Add Simple-Icons and Selfh.st collections

[SeDemal]

Closes #1105

Add Simple-Icons:

Monochrome Icons.
Can change color by adding "/{colour}" at the end of the link, can also be in hex format.

Add Selfh.st icons:

Self-hosting focused collection.
Completes current collections with icons that are not available from other sources.

Refactor:

Change regex function (Wrongly named too btw) with path parse.
Add blob replace: "{1}" -> icon name only and not whole path.
Improve file extension checker

This pushes us over the 10k icons
