doc: simplify ccache instructions

Browse Source 
`ccache` has reasonable defaults for `max_size` and `cache_dir` so
remove instructions to set those things explicitly.

Change fenced code from `console` to `bash` for easier copy/paste.

@ -521,22 +521,18 @@ installing `ccache` can help to greatly reduce build times. Set up with:
On GNU/Linux:
```console
$ sudo apt install ccache # for Debian/Ubuntu, included in most Linux distros
$ ccache -o cache_dir=<tmp_dir>
$ ccache -o max_size=5.0G
$ export CC="ccache gcc" # add to your .profile
$ export CXX="ccache g++" # add to your .profile
```bash
sudo apt install ccache # for Debian/Ubuntu, included in most Linux distros
export CC="ccache gcc" # add to your .profile
export CXX="ccache g++" # add to your .profile
```
On macOS:
```console
$ brew install ccache # see https://brew.sh
$ ccache -o cache_dir=<tmp_dir>
$ ccache -o max_size=5.0G
$ export CC="ccache cc" # add to ~/.zshrc or other shell config file
$ export CXX="ccache c++" # add to ~/.zshrc or other shell config file
```bash
brew install ccache # see https://brew.sh
export CC="ccache cc" # add to ~/.zshrc or other shell config file
export CXX="ccache c++" # add to ~/.zshrc or other shell config file
```
This will allow for near-instantaneous rebuilds even when switching branches.
