Update h2 and flyway

Sadly it is necessary to fix an existing changeset for H2.

+# H2 dumps should be created using the same (or compatible) version of
+# h2 that is used to run the db.
+#
+# Docspell 0.38.0 and earlier uses H2 1.4.x. From Docspell 0.39.0
+# onwards it's 2.1.x.
+#
+# Set the H2 version via an environment variable 'H2_VERSION'.
+# Additionally a user and password are required, set these via env
+# variables H2_USER and H2_PASSWORD. (or modify this script)
+#
+# Creating/restoring a dump requires to specify the database file. H2
+# appends suffixes like '.mv.db' and '.trace.db', but here the base
+# file is required. So if you see a file 'mydb.mv.db', specify here
+# 'mydb' only or a complete JDBC url.
+#
+# The target file or target db must not exist.
+#
+# The dump file contains (H2 specific) SQL that recreates the
+# database. It can be modified if necessary. This SQL script can then
+# be used to restore the database even to a newer version of H2.
