In `@content/en/docs/release/_index.md`:
- Line 6: Update the sentence "Open Cluster Management has approximately a three
to four month release cycle. The current release is `v1.3.1`." to hyphenate the
compound modifier correctly by changing "three to four month release cycle" to
"three- to four-month release cycle" so the phrase reads: "Open Cluster
Management has approximately a three- to four-month release cycle."
