[BUG] Re-exporting into existing datapack clears minecraft tick and load functions

[iphaic]

Describe the bug
Re-exporting into existing datapack clears Minecraft tick and load functions. This was tested using the 1.21.0 export, I am unsure if it occurs on other export versions but it should probably be looked into for 1.21.2 & 1.21.4 as well

To Reproduce

1. Create a blank datapack
2. Export a project (again, this was using export version 1.21.0)
3. Observe that the pack works as intended, and the Minecraft tick and load functions have the appropriate functions
4. Re-export the same project.
5. Notice that the Minecraft tick & load functions have had all functions in the array removed, and all the remains is a blank array

Expected behavior
A re-export should not clear the Minecraft tick and load functions

Can confirm in 1.21.3. I think is overwriting something, Because it disable all my load/tick functions from my datapacks

I've fixed this in v1.6.2.

I think this is a combination of two issues from two different versions:

1. Phiac (AJ v1.6.1) My check for which version was in use to decide between function and functions was checking for versions > 1.21.0, instead of >= 1.21.0.
2. Fanfo (AJ v1.6.0) The overrides override the tick and load functions in this version.
