npm: bump svgo from 3.0.3 to 3.0.4

[dependabot]

Bumps svgo from 3.0.3 to 3.0.4.

Release notes

Sourced from svgo's releases.

v3.0.4

Includes various bug fixes for existing plugins and a new optimization. Also splits removeXMLNS, which removed XLink, into two separate plugins, removeXMLNS and removeXlink.

What's Changed

Default Behavior

• Remove XML Namespace, no longer removes the XLink (xmlns:xlink) namespace. If that is desirable, you should enable the new Remove XLink (removeXlink) plugin, which does more while being safer. By @​TrySound and @​SethFalco in svg/svgo#1535

Bug Fixes

• Convert Path Commands, ignore instances where transform applied via style tag. By @​SethFalco in svg/svgo#1830
• Inline Styles, inline properties with the same specificity in the order that they appear in the stylesheet. By @​SethFalco in svg/svgo#1831
• Inline Styles, don't remove class or id from node if it's traversed in another CSS selector. By @​SethFalco in svg/svgo#1832 and svg/svgo#1836
• Don't trim pre elements in foreignObject. By @​SethFalco in svg/svgo#1796
• Don't crash when encountering @-webkit-keyframes in <style> node. By @​SethFalco in svg/svgo#1826

SVG Optimization

• Convert Path Commands, convert to z command if going back to initial position, or drop z if redundant. By @​KTibow in svg/svgo#1822
• Inline Styles, when inlining a CSS property that's already declared in a presentation attribute of the node, drop the attribute. By @​SethFalco in svg/svgo#1829
• Remove XLink, new plugin that removes the XLink (xmlns:xlink) namespace and migrates from XLink attributes to the SVG 2 equivalent. Disabled by default. By @​TrySound and @​SethFalco in svg/svgo#1535
