Support property placeholders in @⁠Sql script paths

Prior to this commit, paths configured via the scripts attribute in
@⁠Sql were required to be final paths without dynamic placeholders;
however, being able to make script paths dependent on the current
environment can be useful in certain testing scenarios.

This commit introduces support for property placeholders (${...}) in
@⁠Sql script paths which will be replaced by properties available in
the Environment of the test's ApplicationContext.

Closes gh-33114
