Note the following CVE exposure before this PR:

- jinjava 2.5.2
  - CVE-2020-12668, fixed in 2.5.3
  - sonatype-2021-0948, fixed in 2.5.10
- commons-net 3.3
  - CVE-2021-37533, fixed in 3.9
- jsoup 1.10.3
  - CVE-2021-37714, fixed in 1.14.2
  - CVE-2022-36033, fixed in 1.15.3

After this PR, all these are resolved.  jinjava 2.7.1 brings in commons-net 3.9 and jsoup
1.15.3, though jsoup is shaded.  See
https://github.com/HubSpot/jinjava/blob/jinjava-2.7.1/pom.xml#L34 and
https://github.com/HubSpot/jinjava/blob/jinjava-2.7.1/pom.xml#L240.

Use version 2.7.1 of jinjava since it's the first version that fixes HubSpot/jinjava#429 via HubSpot/jinjava#1008.
