Fix spelling inconsistency for `pekudei`

[jacobshilitz]

there is an inconsistency in spelling between pekudei when alone and pikudei when its with vayakheil

I choose pekudei spelling after I saw cabbad spell like this https://www.chabad.org/parshah/default_cdo/aid/15569/jewish/Vayakhel-Pekudei.htm

Thank you for the lib...
