Merge bitcoin/bitcoin#32002: doc: add note to Windows build about stripping bins

c94195c doc: add note to windows build about stripping bin (fanquake)

Pull request description:

  The Windows binaries are particularly big when they contain debug info, closing in on 500mb. Add a note to the Windows build instructions about using `--strip`.

  I haven't tested this (the copying out to WSL). If we don't want to add this note, in favour of [user-presents or similar](bitcoin/bitcoin#30593 (comment)), then we should just close #30593.

  Fixes #30593.

 executables to a directory on the Windows drive in the same directory structure
 as they appear in the release `.zip` archive. This can be done in the following
 way. This will install to `c:\workspace\bitcoin`, for example:
+```shell
+cmake --install build --prefix /mnt/c/workspace/bitcoin
+```
 
-    cmake --install build --prefix /mnt/c/workspace/bitcoin
+Note that due to the presence of debug information, the binaries may be very large,
+if you do not need the debug information, you can prune it during install by calling:
+```shell
+cmake --install build --prefix /mnt/c/workspace/bitcoin --strip
+```
 
 You can also create an installer using:
-
-    cmake --build build --target deploy
+```shell
+cmake --build build --target deploy
