remove extra space

Changelog Entry

To be copied to the draft changelog by merger:

• Random double space in a vg autoindex logging line is now a single space

Description

Running some commands and saw:

[...]
[IndexRegistry] Chunking inputs for parallelism.
[IndexRegistry]  Constructing VG graph from FASTA and VCF input.
[IndexRegistry] Constructing GBWT from VG graph and phased VCF input.
[...]

So I fixed it.

Combined with my other CI failure in #4783 where exactly the opposite pair of statuses happened (fail Mac and pass GitLab) I don't think it's my fault. Not that I thought either of those PRs should have an impact on the tests in general.
