fix: Change shell execution to bash

[moraesjeremias]

Reason for Change

• It was identified that lc up cmd was broken due to a diff shell execution based on Availup script.

Changes

• Change shell execution from sh to bash

Backgound

Availup script was designed to be run by bash, since it uses some bash expressions that can't be interpreted in sh shell.
