Please merge :-)

I think this would be okay as a minor bump for the existing package code. The v1 branch already has the SVGO v3 integrated.

Are there any side-effects from updating to v3?

[stramel]

Thanks for this PR! At this time we're going to forego this and focus on the v1 since this has a workaround and we have published a next version of astro-icon that includes using svgo@v3
