upgrade ccache installed version to 4.6.2

- primary reason: 4.6.2 fixes errors if the user's home directory contains a space
- alternative fix: the CCACHE_DIR env var can be set to something without a space in it, or set to TMP which properly escapes the home dir name
- there may be other issues with spaces in filenames on builds in other parts of ESP-IDF, see https://github.com/espressif/esp-idf/issues/8364 for more info
