Update documenation examples to use multi-line strings.

[vab2048]

I have just come across JDBI and reading through the doucmentation saw examples like this, escaping quotes:

List<User> users = jdbi.withHandle(handle -> {
    handle.execute("CREATE TABLE \"user\" (id INTEGER PRIMARY KEY, \"name\" VARCHAR)");

Since you are now moving to a Java 17 baseline these can be replaced with multi-line strings/text blocks which would make the SQL string like this:

List<User> users = jdbi.withHandle(handle -> {
    handle.execute("""
      CREATE TABLE "user" (id INTEGER PRIMARY KEY, "name" VARCHAR)""");

I think even though it adds an extra line, it is clearer. Would you be amenable to me raising a PR changing all instances of strings containing escaped quotes to multi-line strings?

Yes, that sounds like a good idea to me! Thank you

Getting a PR would be great, thank you! We might hold off merging till we actually moved to 17. If we need to push another 3.49 release, then we would have to undo.
