Release Hail Table format of SV and CNV data

[ch-kr]

We currently only release VCFs for the SV and CNV data. It would be beneficial to release the transformed Hail Tables containing these data as well, similar to the v4 browser variants HT release.

I'll reach out to the CNV/SV teams to help with documentation for this release, since we should update this page with descriptions of these new tables

Adding comment to add checklist of release steps:

• Get documentation of fields in SV/CNV tables from Xuefang and Jack
• Rename populations in HTs to gen_anc_grps prior to release (request for browser team to rename this field for public release)
• Add descriptions to browser HTs help doc
• Review/approve/merge PR adding descriptions to help doc (this is ready to be merged when closer to release)
• Add sections and links to these HTs on downloads page
• Stage HTs to public staging bucket once PR above is approved (will need someone from browser team to do this due to permissions)
• Sync HTs from GCP to AWS (KC will do this)

adding a comment here to add another two items:

• Remove qual and filters from CNV HT prior to release
  ^I checked with Jack, and he didn't add these fields, nor do they appear to be displayed: https://gnomad.broadinstitute.org/variant/18714__DUP?dataset=gnomad_cnv_r4
• Release changelog entry (approved and ready to go)

@ch-kr looking into this now

Per @ch-kr we're not converting the v2 SVs for now, which we may revisit if there turns out to be demand for them.
