Remove deprecated version attribute from top svg element #1701
Description
Per MDN docs on the <svg version> attribute
https://developer.mozilla.org/en-US/docs/Web/SVG/Attribute/version
Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.
This text suggests to me it is safe to remove when optimizing for fewer total characters.
