[susanev]

ref: https://github.com/pulumi/docs/pull/9086

while we are in this area, we should make sure the changes i made will generate them in the right place; since the cli docs moved

maybe relevant https://github.com/pulumi/pulumi-hugo/blob/master/themes/default/layouts/shortcodes/pulumi-command.html

• verify change made here https://github.com/pulumi/pulumi/blob/master/pkg/cmd/pulumi/gen_markdown.go also fixes links in see also section
• need to add aliases into markdown generation
• test that generation, ahead of the next cli release
• turn off auto-merge on next cli release; just to double confirm we didn't totally break cli docs
• reach out to Justin with questions slash for review
• docs workflow file: https://github.com/pulumi/docs/blob/master/.github/workflows/pulumi-cli.yml
