This ticket is about realizing what we found during T300040: Investigation: update Maki icons .

To do:

• Adjust size of icons to match previous version (at s/m/l sizes)
• Center icons.
• Verify that alphanumeric markers are centered.
• Agree on how missing icons from maki 0.5.0 will be aliased.
• Dynamic and static maps must be consistent.

Should be separate sub tasks:

• Document new icons, as well as aliased icons from maki 0.5.0, updating the help page.
• Deploy to the beta cluster so we can validate.
