docs: fix bare infinitive 'allows to fill' in fill_run.Rd

[LeonidasZhak]

Summary

Fixed bare infinitive grammatical error "allows to fill" in the @param run_for_first description of fill_run().

Problem

The verb "allow" requires a gerund (allow + -ing) or a noun phrase before "to" (allow + someone + to). The current documentation states:

run_for_first = TRUE allows to fill all initial NA with nearest non-NA value.

This is a bare infinitive error.

Fix

Changed "allows to fill" to "allows filling":

run_for_first = TRUE allows filling all initial NA with nearest non-NA value.

Stata Migration Relevance

The fill_run() function is useful for Stata users migrating to R, as it provides functionality similar to Stata's fill command for carrying forward values. Clear documentation of the run_for_first parameter helps Stata users understand how to handle initial missing values, which is a common data cleaning operation.
