vcf: Valid contig ID in failed example

[zaeleus]

test/vcf/4.3/failed/failed_meta_contig_003.vcf has a contig ID (1.*) marked as illegal but matches the name regex.

§ 1.4.7 "Contig field format" (2022-08-22):

[Contig names] match the following regular expression:

[0-9A-Za-z!#$%&+./:;?@^_|~-][0-9A-Za-z!#$%&*+./:;=?@^_|~-]*

VCF's rules for contig IDs were changed in PR #379 (merged in March 2020) to align them with SAM's rules. As noted in §7.1, the main observable difference was relaxing the previous VCF prohibition on colons (in all VCF versions) and non-first * characters (only done explicitly in 4.3).

These test files were ported from EBI's VCF Validator, their origin predates this contig ID change, and they were insufficiently re-reviewed when PR #491 was merged in April 2021.

So this should be corrected to be a passing test file. Also requiring updating in the light of 2020's change:

• 4.1/failed/failed_body_chrom_001.vcf
• 4.2/failed/failed_body_chrom_001.vcf
• 4.3/failed/failed_body_chrom_001.vcf
• 4.3/failed/failed_body_chrom_004.vcf
