Auto merge of #11170 - tgross35:undocumented-unsafe-blocks-defaults, r=Centri3

Browse source 
Change defaults of `accept-comment-above-statement` and `accept-comment-above-attributes`

This patch sets the two configuration options for `undocumented_unsafe_blocks` to `true` by default: these are `accept-comment-above-statement` and `accept-comment-above-attributes`. Having these values `false` by default prevents what many users would consider clean code, e.g. placing the `// SAFETY:` comment above a single-line functino call, rather than directly next to the argument.

This was originally discussed in https://github.com/rust-lang/rust-clippy/issues/11162

changelog: [`undocumented_unsafe_blocks`]: set
`accept-comment-above-statement` and `accept-comment-above-attributes` to `true` by default.
