## Summary of Changes
Fixed common doubled word typos (e.g., "to to", "of of") in comments and
documentation strings across various packages. These changes are purely
cosmetic and do not affect code logic.

## Summary of Changes
The PLY file format does not support 64 bits (signed/unsigned) integers.
In the overload of the writer specific to `Surface_mesh`, we try to
write all property maps with value types compatible with the PLY file
format (char, uchar, etc.).
We also tolerate 64 bits signed / unsigned integers, but used to cast it
to int32 / uint32:
```cpp
{
Int64_map pmap;
boost::tie(pmap, okay) = sm.template property_map<Simplex,boost::int64_t>(prop[i]);
if(okay)
{
os << "property int " << name << std::endl;
printers.push_back(new internal::Simple_property_printer<Simplex,Int64_map,boost::int32_t>(pmap));
continue;
}
}
```
In https://github.com/CGAL/cgal/pull/6575, the code was factorized, but
the conversion to 32 bits was accidentally lost
(https://github.com/CGAL/cgal/commit/aa9f5215c4afa79d29cc5491d1d690cd2ed7a142).
Hence, we were writing 8 bytes values (while announcing 4 bytes values)
and writing a property map with value type a 64 bits integers (or a
range of 64 bits integers) would make the file unreadable.
The PR re-introduces the conversions, and also removes the recursion of
the function.
The bug is from CGAL 5.5, but we have recent changes to PLY I/O
introducing named parameters and whatnot that make it a little tedious
to backport so I will wait to see if there is a need.

/mnt/testsuite/include/CGAL/IO/PLY/PLY_writer.h:296:30: warning:
loop variable 'v' of type 'const unsigned int&' binds to a temporary
constructed from type 'const long unsigned int' [-Wrange-loop-construct]
296 | for(const ElementType& v : vec)
This is because ElementType is not the value type of the vector,
but the data type that we write, and for 64 bits integer,
we convert to 32 bits. So in that case, we can't cast yet.
