`npm run build:dev` creates CSS files in the blocks folder of an SVN checkout.

After running npm run build:dev on trunk and the 6.3 branch, a number of uncommitted CSS files are created that are not required for commit.

I think the props list for SVN needs to be updated to ignore the files. After running the command, svn status shows:

$ svn status
?       src/wp-includes/blocks/details/editor-rtl.css
?       src/wp-includes/blocks/details/editor-rtl.min.css
?       src/wp-includes/blocks/details/editor.css
?       src/wp-includes/blocks/details/editor.min.css
?       src/wp-includes/blocks/details/style-rtl.css
?       src/wp-includes/blocks/details/style-rtl.min.css
?       src/wp-includes/blocks/details/style.css
?       src/wp-includes/blocks/details/style.min.css
?       src/wp-includes/blocks/footnotes/style-rtl.css
?       src/wp-includes/blocks/footnotes/style-rtl.min.css
?       src/wp-includes/blocks/footnotes/style.css
?       src/wp-includes/blocks/footnotes/style.min.css
