### Describe Your Changes Fix many spelling errors and some grammar, including misspellings in filenames. The change also fixes a typo in metric `vm_mmaped_files` to `vm_mmapped_files`. While this is a breaking change, this metric isn't used in alerts or dashboards. So it seems to have low impact on users. The change also deprecates `cspell` as it is much heavier and less usable. --------- Co-authored-by: Andrii Chubatiuk <[email protected]> Co-authored-by: Andrii Chubatiuk <[email protected]>
