[PATCH v2] ref-manual: update supported distro versions

[michael.opdenacker]

From: Michael Opdenacker <michael.opdenacker@bootlin.com>

- Update according to changes in SANITY_TESTED_DISTROS
  (meta-poky/conf/distro/poky.conf)

- No longer declare as "Supported" the distributions versions
  which are End of Life for their vendors, as some of them
  (Ubuntu for example) ship updates to subscribers only,
  which the Yocto Project has no access to.

- List distribution versions which were previously tested
  for the branch of the Yocto Project being considered
  (should be an empty list on master, until the next
  release is made).

Signed-off-by: Michael Opdenacker <michael.opdenacker@bootlin.com>

Changes in V2:
- Update with recent update of SANITY_TESTED_DISTROS
  Thanks to this, more recent versions are declared as supported.

+Note that the Yocto Project doesn't have access to private updates

+limited value if you have access to such updates.
