Although it makes a bunch of dummy empty commit, a dump file contains
empty revisions can increase youngest revision number keeping content
of the tree empty.

e.g. A shell script to make a repositoy contains
10 empty revisions:
[[[
#!/bin/sh

repos_uuid='c68ffc52-e6c1-4053-9b3b-6e67a0e223f2'
rev0_date='2023-09-01T10:22:50.036256Z' # This should be just 27 letters.
number_of_commits=10

produce_dump()
{
cat <<DUMP_HEAD_END
SVN-fs-dump-format-version: 2

UUID: ${repos_uuid}

Revision-number: 0
Prop-content-length: 56
Content-length: 56

K 8
svn:date
V 27
${rev0_date}
PROPS-END

DUMP_HEAD_END

rev=0
while [ $rev -lt $1 ]; do
rev=$(($rev+1))
cat <<REV_END
Revision-number: $rev
Prop-content-length: 10
Content-length: 10

PROPS-END

REV_END
done
}

svnadmin create new_repo
produce_dump "${number_of_commits}" | svnadmin load -q new_repo
svnadmin info new_repo
]]]
