Fix capitalization on buttons for the pipelines page
On the CI/CD Pipelines page the two buttons use capitalization that is inconsistent with the capitalization in the rest of the product. ![Pipelines___GitLab_org___GitLab___GitLab](data:image/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==)
The buttons should read "Run pipeline" and "CI lint".
On the Jobs page, the button is correctly labeled "CI lint".
