Make the template example rows consistent with the technical notes

[fretchen]

In the template we have a number of rows with examples. My understanding is that they should be in agreement with the technical guidelines. Otherwise they might confuse the user and also fail in automatic validation tests...

This really starts to become obvious as we start work on automatic validators as for example in #76. There the validator currently fails on numerous rows with data. The current errors are:

Row 3 is valid
Row:  4
Error in row: 4
'approximate (admin unit)' is not one of ['exact', 'approximate']
Row:  5
Error in row: 5
'longitude' is a required property
Row:  6
Error in row: 6
'kfwProjectNoINPRO' is a required property
Row:  7
Error in row: 7
'kfwProjectNoINPRO' is a required property
Row:  8
Error in row: 8
'kfwProjectNoINPRO' is a required property
Row:  9
Error in row: 9
'kfwProjectNoINPRO' is a required property
Row:  10
Error in row: 10
'kfwProjectNoINPRO' is a required property
Row:  11
Error in row: 11
'kfwProjectNoINPRO' is a required property
Row:  12
Error in row: 12
'kfwProjectNoINPRO' is a required property
Row:  13
Error in row: 13
'kfwProjectNoINPRO' is a required property
Row:  14
Error in row: 14
'kfwProjectNoINPRO' is a required property
Row:  15
Error in row: 15
'kfwProjectNoINPRO' is a required property
Row:  16
Error in row: 16
'kfwProjectNoINPRO' is a required property
Row:  17
Error in row: 17
'kfwProjectNoINPRO' is a required property
Row:  18
Error in row: 18
'kfwProjectNoINPRO' is a required property

From what I can see all these complaints are valid. I would think that each entered line in the example template should be valid, but maybe three data lines are also sufficient ? @Maja4Dev I think that this one is most likely close to you no ?
