Inform about aliases in auditwheel repair --help

[mayeut]

e.g.

Legacy tags are still supported and alias the new PEP600 tags:
  - manylinux1_x86_64 is an alias for manylinux_2_5_x86_64
  - manylinux2010_x86_64 is an alias for manylinux_2_12_x86_64
  - manylinux2014_x86_64 is an alias for manylinux_2_17_x86_64

Full output for now is:

usage: auditwheel repair [-h]
                          [--plat {linux_x86_64,manylinux_2_5_x86_64,manylinux_2_12_x86_64,manylinux_2_17_x86_64,manylinux_2_24_x86_64,manylinux1_x86_64,manylinux2010_x86_64,manylinux2014_x86_64}]

Vendor in external shared library dependencies of a wheel.

positional arguments:
  WHEEL_FILE            Path to wheel file.

optional arguments:
  -h, --help            show this help message and exit

                        Desired target platform. (default:
                        "manylinux_2_5_x86_64") Legacy tags are still
                        supported and alias the new PEP600 tags.
                        manylinux1_x86_64 is an alias for
                        manylinux_2_5_x86_64. manylinux2010_x86_64 is an alias
                        for manylinux_2_12_x86_64. manylinux2014_x86_64 is an
                        alias for manylinux_2_17_x86_64.
  -L LIB_SDIR, --lib-sdir LIB_SDIR
                        Subdirectory in packages to store copied libraries.
                        (default: ".libs")
  -w WHEEL_DIR, --wheel-dir WHEEL_DIR
                        Directory to store delocated wheels (default:
                        "wheelhouse/")
  --no-update-tags      Do not update the wheel filename tags and WHEEL info
                        to match the repaired platform tag.
  --strip               Strip symbols in the resulting wheel
  --only-plat           Do not check for higher policy compatibility

Legacy tags are still supported and alias the new PEP600 tags.
manylinux1_x86_64 is an alias for manylinux_2_5_x86_64. manylinux2010_x86_64
is an alias for manylinux_2_12_x86_64. manylinux2014_x86_64 is an alias for
manylinux_2_17_x86_64.

Formatting is messy.

@mayeut What do you think about moving the entire list of valid platforms and the explanation about aliases to the bottom, outside of the --plat help? I find the list of platforms hard to read as a list as we have so many now.

Something like this:

...
--plat <platform>            See the available platforms under the PLATFORMS section below.
...

PLATFORMS
These are the possible target platform tags, as specified by PEP 600. 
Note that old, pre-PEP 600 tags are still usable and are aliased as listed below.

- linux_x86_64
- manylinux_2_5_x86_64 (aliased as manylinux1_x86_64)
...

This might be cleaner now:

usage: auditwheel repair [-h] [--plat PLATFORM] [-L LIB_SDIR] [-w WHEEL_DIR]
                         [--no-update-tags] [--strip] [--only-plat]
