Add autoload to the function responsible for dynamic blocks

### OS/platform

MacOS

### Emacs version and provenance

Emacs 29

### Emacs command

emacs

### Org version and provenance

9.7.17

### org-ql package version and provenance

20241107.345

### Actions taken

- open emacs
- autoload org-ql using the instructions in the github page
` (use-package org-ql
:after org)`
- try to expand a dynamic block

### Observed results

org-update-dblock: Symbol’s function definition is void: org-dblock-write:org-ql

Loading org-ql-search manually solves the problem and makes the dynamic block to work, so this is not a path problem

### Expected results

The dynamic block should execute even if org-ql has not been loaded before. It seems to be missing an autoload statement
