Use std package to work with templates

[ShoshinNikita]

Hello. I noticed swag uses github.com/alecthomas/template instead of text/template. Is there any reason to use this third-party dependency? I couldn't find any usage of its main feature:

a backslash immediately after a closing delimiter will delete all subsequent newlines until a non-newline

I think it would be better to use the std package. Especially because code of github.com/alecthomas/template hasn't been updated since 2015

I'd like to +1 this issue. An extra dependency on a fork of an out-of-date version of standard library module, last updated in 2015. Is there really an engineering need for this, please? 🙃

UPDATE: Just found PR #891 had been merged. Thank you! Looking forward to a tagged release without this dependency ❤️
