Clean up Bikeshed metadata

[rakuco]

• Remove custom "Bug Reports" key, this is added automatically by the "Repository" key (i.e. there is a "GitHub" link under "Feedback").
• "Test Suite" is a valid key in Bikeshed, so there is no need to declare it as custom. Follow Bikeshed's documentation and provide a URL rather than a <a> block.
• Remove custom Conformance section, let Bikeshed generate it from dap's boilerplate in Bikeshed's spec-data.
• There is no need to explicitly tell Bikeshed not to include an issues index, as Bikeshed does not add it due to the lack of an "issues" class in CSS.

Thanks! There are probably quite many Bikeshed-based specs that'd benefit from the same treatment now that Bikeshed has these features built in and no custom magic is needed anymore.
