Possible bug in the OTP version management

[sylane]

When having a build section and a specific local version of OTP with a less defined version in the rebar.config, it seems it is confusing the OTP version selection:

rebar.config:

{grisp, [
    {otp, [{version, "26"}]},
    {platform, grisp2},
    {build, [
       {toolchain, [
           {docker, "grisp/grisp2-rtems-toolchain"}
       ]}
    ]},
   ...
]}.
...

Built OTP:

❯ ls -la _grisp/grisp2/otp
total 0
drwxr-xr-x  3 sebastien  staff   96 Aug  1 16:33 .
drwxr-xr-x  3 sebastien  staff   96 Aug  1 16:33 ..
drwxr-xr-x  4 sebastien  staff  128 Aug  1 16:47 26.2.5.2

When building:

===> Compiling grisp_demo
* Resolving OTP version
    26.2.5.3 (requirement was "26")
* Using custom OTP (e2b108e0)
===> Unexpected error: {error,
                                              {rlx_config,
                                               {bad_system_libs,
                                                "/Users/sebastien/.../_grisp/grisp2/otp/26.2.5.3/install/lib"}}}
