Disabling Try support in old lando

[Olivier (shtrom) Mehani]

Hi all,

tl;dr: We are tentatively turning of Try support in old Lando. Please reach out to #Conduit on Matrix if you are adversely impacted.

Since we pointed `mach` to submit Try jobs via new lando a couple of months ago, the vast majority of the job has been going through the new instance with no issue [0].

There were a few stragglers, mainly due to ESRs. ESR140 has been pointed to new lando last week [1], which should take care of the remaining dependency on the old instance.

If you find this change causes issues in your work, please reach out to #Conduit on Matrix, so we can consider options, starting with temporarily re-enabling the support while we work through the root cause of the issues.

Cheers!
