PEP Command Fails on Empty Metadata

[sco1]

Currently, the PEP command assumes that if a metadata field is present in the PEP's summary table that the value is populated:

bot/bot/cogs/utils.py

Lines 64 to 72 in 74d9905

	# Add the interesting information
	if "Status" in pep_header:
	pep_embed.add_field(name="Status", value=pep_header["Status"])
	if "Python-Version" in pep_header:
	pep_embed.add_field(name="Python-Version", value=pep_header["Python-Version"])
	if "Created" in pep_header:
	pep_embed.add_field(name="Created", value=pep_header["Created"])
	if "Type" in pep_header:
	pep_embed.add_field(name="Type", value=pep_header["Type"])

However, this is not always the case, e.g. PEP 249:

Because of this, the embed field's value can be provided an empty string, causing an exception to be raised:

HTTPException: 400 BAD REQUEST (error code: 50035): Invalid Form Body
In embed.fields.1.value: This field is required

To fix this, there should be a catch for empty values to prevent a field being added if there's no value to populate.
