devel-docs: update a reference to 32-bit pointers. 

Though the description of the POINTER type clearly tells of the new type
size, it was still refered as 32-bit only in this introductory text.
Let's fix this.

References _between_ structures in the XCF file take the form of
32-bit "pointers" that count the number of bytes between the beginning of
the XCF file and the beginning of the target structure. Note that therefore
the maximum address of a layer, channel, hierarchy or tile set is 2^32 - 1,
i.e. at 4 GB. Everything after will be lost. Currently this doesn't play a
role yet.

Pointers used to be 32-bit data. Since the maximum address of a layer,
channel, hierarchy or tile set was 2^32 - 1, i.e. at 4 GB, the maximum
size for XCF images before GIMP 2.10.0 was quite limited.
Now pointers can be 64-bit, allowing files big enough for any image
produced by current technology. See the chapter "Basic data types" for
description of the POINTER type.
Each structure is designed to be written and read sequentially; many
contain items of variable length and the concept of an offset _within_
