could you check for cable-lengths for T1?

pls check if cable-length/speed are included in pg_profile_lookup.ini

I was not aware there are new cable-length/speed for the hwsku. Which ones need to be added?
Here are the existing ones: https://github.com/sonic-net/sonic-buildimage/blob/master/device/arista/x86_64-arista_7060x6_64pe_b/Arista-7060X6-64PE-B-P32O64/pg_profile_lookup.ini

@dakotac-arista I believe we need to add 300m cable length for the T1 hwsku. We can handle it in another PR later.

Why I did it
Arista-7060X6-64PE-B-P32O64 will also be used for a T1 role and they wanted to reuse the QoS settings.
Work item tracking
How I did it
Using a symlink to point to the buffer default values values for the LT2 role.
This will make sure any fixes for LT2 will be carried over.
The same bcm config file with applied QoS settings is already being used.
How to verify it
ls -alshowsbuffers_defaults_t1.j2 -> buffers_defaults_lt2.j2Tested on DUT and confirmed the buffer pools/profiles were populated and no issues during sanitize.
