file_min_digits: 5->6 (#2385)

* file_min_digits: 5->6

100k+ step runs are quite common in WarpX. To simplify
post-processing scripts, increase the default to pad to 6 digits.

This might break some hand-written scripts that use `?????`
wild-cards over `*` wildcards in regex and thus need to be updated.
But it at the same time simplifies regexes for analysis of data
series and listing of such file series.

* Checkpoint-Restart Tests: 5 Digits

`regtest.py` in `regression_testing` hard-codes 5 digits:

* PICMI Restart Tests: `warpx_file_min_digits = 5`

Same as other CI restart tests: hard-coded value in regression
suite makes this necessary.
