fix(transformer/styled-components): fix block comment containing expression in CSS minification

[overlookmotel]

Fix handling block comments which contain an expression. Previously if that block comment ended exactly before another expression, the comment wouldn't be considered closed, and all remaining parts of the template literal would be removed.

Input:

styled.div`${x}/* ${y} */${z}`

Previous output post-minification:

styled.div`${x}`

After this PR:

styled.div`${x}${z}`

This bug was introduced way back in #12224 (my fault!), but had gone unnoticed.
