MDEV-27955 main.func_json_notembedded test fails on out-of-memory

Browse Source 
Uses 500M+ of memory by repeating an 8 byte sequence 62.5M times.

Reduce the number of repeats on string reduced by 100 times.

Tested by applying against the reverted MDEV-24909 code. 1000 times
reduction was too much, but 100 still managed to trigger the bug.
