Add API sorting support

[caixingyue]

For some API groups, I want to sort the APIs in the group so that some APIs that users want to see first are placed in front.

Sorting rules: add x-position to the API and fill in the sorting number. When generating the sidebar.ts file, you can give priority to writing this part of the API according to the number. If there is no x-position, you can sort it according to the original plan.

For example, I might want to rank uploads an image first,Find pet by ID second, and the rest as you wish.
