4.3 currently fails to build due to dependency issues and is not yet available
as a docker image (probably for that reason)

we don't use it

our posts don't have a time of day, so it's quite pointless. iso 8601 dates ftw

it's broken garbage that miserably tries to implement a minifier in liquid…

merely prepending the site.url to the path causes issues when the baseurl is set to /.
in that case, the resulting url would be "//path/to/post", which browsers interpret as "https://path/..."

unortunately jekyll sets the page date to the current time when the site is generated if no specific date is set
this check will skip showing the date if it matches the built time

Fix various

`right` already contains the closing tag

Using "paginate_path: /page/:num/" to generate "/page/2/" paths would still generate invalid
pagination links to "/page2/"

When using the theme starter, which uses a git submodule,
assets loaded from that submodule are "untracked" files in the pages branch working tree.
The build can fail at this line due to Git, saying "the following untracked working tree files would be overwritten by checkout".

Adding `-f` forces the checkout, overwriting all files.
The other deploy steps then take over and rewrite the files as needed.
