Docs: Link to Field Tranforms on System/Fields is broken

[your-sudden-death]

On the page https://docs.directus.io/reference/system/fields/
the link to field tranforms yields a 404. Does this doc page even exist?

It does used to exist, just unfortunately got lost during the major docs rework in #9071. Linking the old file here so that we can lift it off from there later: https://github.com/directus/directus/blob/a257f324c0b2b2befae3ffe4df50ce2949412067/docs/reference/field-transforms.md

As there has been some changes to the naming of the transforms recently, in case you're wondering what are the latest ones, you can view them over here:
