Fix: use at least permission level 2 when checking permissions using permissions API (#393)

This PR makes a small fix to an oversight I made in my 26.2 update PR
(#391). I had accidentally removed the line of code that results in
checking at least permission level 2 when checking permissions using the
permissions API (see
[this](https://github.com/John-Paul-R/Essential-Commands/blob/399e0504d3ff73c944ab8fcdde0d9d332a1f0f31/src/main/java/com/fibermc/essentialcommands/ECPerms.java#L136)
line of code before the 26.2 update). This PR re-introduces that
behaviour.
