Fix height attribute for spacer block

[aledesma-godaddy]

The spacer block has an error when used with the Layout Selector component from CoBlocks with layouts hosted here in Go. Specifically some Home and a contact layout have spacer blocks with a numeric height number. This block actually expects to see a string value now like '20px' for example.

Tested the spacer layouts in local development environment.
