Update composer.json to fix Symfony security advisory

[JeroenSchrader]

See This Github link for more details on the security advisory.

Currently when trying to run composer install with v1.1 set as a requirement, composer gives the following error:

Problem 1
- Root composer.json requires abantecart/ups-php 1.1.0 -> satisfiable by abantecart/ups-php[1.1.0].
- abantecart/ups-php 1.1.0 requires symfony/process v7.3.0 -> found symfony/process[v7.3.0] but these were not loaded, because they are affected by security advisories ("PKSA-rkkf-636k-qjb3"). Go to https://packagist.org/security-advisories/ to find advisory details. To ignore the advisories, add them to the audit "ignore" config. To turn the feature off entirely, you can set "block-insecure" to false in your "audit" config.

The security advisory has been resolved in version 7.3.11 so this removes the composer error.
