Error: "continue" targeting switch is equivalent to "break"

[bookin]

On PHP version >= 7.3 you can see error:
"continue" targeting switch is equivalent to "break". Did you mean to use "continue 2"?
That linked to:

df-core/src/Database/Schema/ColumnSchema.php

Line 124 in 110ea47

continue;

Seems enough just change it to continue 2;
