feat(docs): fix doc generation

[haarchri]

Description of your changes

follow up for
#238
and revert from
#244

the page_title is different for provider-vault then to other providers
page_title: "Vault: vault_ad_secret_backend_library resource"
for that reason i added a small code path to make the example generation working

Fixes #

I have:

• Read and followed Crossplane's contribution process.
• Run make reviewable to ensure this PR is ready for review.
• Added backport release-x.y labels to auto-backport this PR if necessary.

How has this code been tested

rerun make generate in upbound official-providers for aws, gcp and azure

crossplane-contrib/provider-upjet-aws#806 (we have a small diff in config/provider-metadata.yaml because some markdown pages using ' instead of " and the new version fixed this)
crossplane-contrib/provider-upjet-gcp#347
crossplane-contrib/provider-upjet-azure#502
crossplane-contrib/provider-pagerduty#18 (we have a small diff in config/provider-metadata.yaml because some markdown pages using ' instead of " and the new version fixed this)

https://github.com/upbound/provider-vault/pull/7/files
here we see that all examples now generated:

Thanks @haarchri for making the example generation pipeline applicable to more providers and for validating it for the official providers. Very much appreciated.
