(MODULES-11902) Include puppet 8.0.0 and do a release for puppetlabs-sqlserver

[SugatD]

Summary

• Puppet 8 support was accidentally scoped to strictly greater than 8.0.0 (>8.0.0 < 9.0.0) in PR (CAT-2393) Puppetcore update  #492, excluding the 8.0.0 release itself. Corrected metadata.json requirements to >=8.0.0 < 9.0.0 so puppet 8.0.0 is included.
• CI's dependency-checker step was failing because puppetlabs/stdlib released 10.0.1, which fell outside the module's declared upper bound (< 10.0.0). Widened the puppetlabs/stdlib dependency requirement to >= 8.4.0 < 11.0.0 to include current stdlib releases.

Checklist

• metadata_lint passes
• dependency-checker passes
• syntax/lint passes
• Manually verified

Notes

• The Windows-*, puppetcore8-nightly acceptance checks fail, but this is a pre-existing, unrelated infrastructure issue (also fails on PR (MODULES-11838) Update link to Puppet modules contributing documentation #504, merged before this change): the third-party puppet_agent module's bootstrap manifest references the unsupported top-scope fact ::osfamily against Puppet 8.

@SugatD : This is blocking tests from being able to run. Is there anything blocking us from moving forward with this?

[SugatD]

@jst-cyr Since some of the acceptance were failing, we wanted to make sure that the bump of stdlib is working properly. So was working on #507 to fix the existing errors.
Will get this merge ASAP.
