fix: Fix Kalisa's Grace crit chance modifier not working.

[michelrtm]

Fixes #2813

Description of the problem being solved:

Kalisa's Grace Crit Chance modifier wasn't supported as per the linked issue.

Steps taken to verify a working solution:

• Verified Crit Chance is unmodified when the item is added to the build
• Changed the Mana Spent recently to 800
• Verified that the Crit Chance modifier had increased by 2%

Link to a build that showcases this PR:

N/A

Before screenshot:

Modifier is unsupported.

After screenshot:

Modifier now supported.

When mana spent is below threshold, no crit chance is added.

When mana is above threshold, crit chance is increased by 2%.

The correct in-game wording is for 2 seconds after Spending a total of 800 mana btw, so the unique wording needs to be updated as well (on top of using correct wording for parsing)

Thanks @deathbeam , I'll include that fix in this PR too.

@deathbeam I've just pushed some changes to fix the item's Mod and for the changes to work with the new Mod text. I've ran through the same steps as in the PR description and still experiencing the same success. I was trying to test the original mod parsing with the 4 seconds but it seemed to be for the Weave the Arcane Trickster ascendancy passive which has been removed from the tree.
